Introduction to the chapter Thank you for choosing the OLinuXino single board computer from Olimex! This document provides a user’s guide for the Olimex OLinuXino board. As an overview, this chapter gives the scope of this document and lists the board’s features. The document’s organization is then detailed. The OLinuXino development board enables code development of applications running on the microcontroller A13, manufactured by Allwinner Technology from China. OLinuXino is an open-source, open-hardware project and all documentation is available to the customer. 1.1 Features • A13 Cortex A8 processor at 1GHz, 3D Mali400 GPU • 256 MB RAM (128Mbit x 16) • 5VDC input power supply, noise immune design • 1 USB Host • 1 USB OTG which can power the board • SD-card connector for booting Linux or Android image • VGA video output – 800 x 600 maximum resolution • LCD signals available on connector so you still can use LCD if you disable VGA/HDMI • Audio output • Microphone input pads (no connector) • 1 User key • 4 Mount holes • UEXT connector for connecting additional UEXT modules like Zigbee, Bluetooth, relays, etc • GPIO connector with 68/74 pins and these signals : 17 for adding NAND flash; 22 for connecting LCDs; 20+4 including 8 GPIOs which can be input, output, interrupt sources; 3x I2C; 2x UARTs; SDIO2 for connectinf SDcards and modules; 5 system pins: +5V, +3.3V, GND, RESET, NMI • (Optional low cost 7" or 4.8'' LCD with/without touchscreen) 1.2 Target market and purpose of the board The boards from the OLinuXino family are powerful and easy to setup. They are suitable for embedded programming enthusiasts, Linux and Android gadget fans and also professionals (since its low cost makes it very good solution for application orientated embedded systems). The main usage of the board is software embedded development without the urge of understanding perfectly the hardware. The strong points of the boards are the processor speed, the mobility of the board and the low ratio price to productivity. Page 5 of 29 OLIMEX© 2012 A13-OLinuXino-MICRO user's manual A13-OLinuXino-MICRO aims at the lowest possible cost while maintaining the key OLinuXino features. It is suitable for cases when a number of boards are used. It is suitable for different Linux distributions. Customers have full access to the technical documentation of the board. The software is released under General Purpose License and the board is considered open-hardware. 1.3 Board variants There are two major board variants. According to the names: A13-OLinuXino and A13-OLinuXino- MICRO. The base model has also two flavors: A13-OLinuXino and A13-OLinuXino-MICRO-WIFI. The first one is the base model that goes without any operating system image on board, while the second has two additional components – a WIFI module on the board and NAND memory with stored Android image. The A13-OLinuXino-MICRO is the other less populated but cheaper board in the family. It also lacks Android out-of-the-box. 1.4 Organization Each section in this document covers a separate topic, organized as follow: – Chapter 1 is an overview of the board usage and features – Chapter 2 provides a guide for quickly setting up the board and software notes – Chapter 3 contains the general board diagram and layout – Chapter 4 describes the component that is the heart of the board: the A13 – Allwinner processor – Chapter 5 is an explanation of the control circuitry associated with the microcontroller to reset. Also shows the clocks on the board – Chapter 6 covers the connector pinout, peripherals and jumper description – Chapter 7 provides the schematics – Chapter 8 contains the revision history, useful links and support information Page 6 of 29 OLIMEX© 2012 A13-OLinuXino-MICRO user's manual CHAPTER 2: SETTING UP THE OLINUXINO BOARD 2. Introduction to the chapter This section helps you set up the OLinuXino development board for the first time. Please consider first the electrostatic warning to avoid damaging the board, then discover the hardware and software required to operate the board. The procedure to power up the board is given, and a description of the default board behavior is detailed. 2.1 Electrostatic warning OLinuXino is shipped in a protective anti-static package. The board must not be exposed to high electrostatic potentials. A grounding strap or similar protective device should be worn when handling the board. Avoid touching the component pins or any other metallic element. 2.2 Requirements In order to set up the A10s-OLinuXino-Micro optimally one or more additional items may be used. They might be generally placed in three categories: Required - items that are needed in order to achieve minimum functionality; Recommended – items that is good to have in order to be able to interact with the most important of the features of the board; Required items: - 5V, 5W required (5V @ 1A) – for optimal power - LCD (preferably with touchscreen panel) display for the LCD_CON OR TV monitor with RGB port (or suitable connector) - USB hub (for splitting the USB) – else you will be unable to connect your USB devices - A USB mouse – if you use touchscreen LCD you might skip the mouse - A Micro SD card with Linux image – you can download and upload the image on any 2GB or bigger Micro SD card – the image can be downloaded from the wiki article (https://www.olimex.com/wiki/A13-OLinuXino-MICRO) Recommended items: - USB keyboard – for convenience with text input - USB-SERIAL-CABLE-F – for serial communication with UART1 connector (note that it has to be female) - USB-MINI-CABLE – for connecting with the USB OTG and being able to firmware update to power A13-OLinuXino-MICRO - Wireless internet connectivity or USB modem – for browser access and access to the Android market Some of the above items can be purchased by Olimex, for instance: Page 7 of 29 OLIMEX© 2012 A13-OLinuXino-MICRO user's manual SY0605E - power supply adapter 5V/1A for A13-OLinuXino-MICRO USB-SERIAL-CABLE-F - USB serial console cable female USB-MINI-CABLE – standard USB type A to USB type mini cable A13-OLinuXino-MICRO-SD - SD card with ready and tested Debian – https://www.olimex.com/Products/OLinuXino/A13/A13-OLinuXino-MICRO-SD/. Note the cards for A13-OLinuXino and A13-OLinuXino-WIFI A 10.1''; 7'' and 4.3'' LCD displays with optional touch screen panels are available for purchase also: https://www.olimex.com/Products/OLinuXino/A13/A13-LCD10/ https://www.olimex.com/Products/OLinuXino/A13/A13-LCD10TS/ https://www.olimex.com/Products/OLinuXino/A13/A13-LCD7/ https://www.olimex.com/Products/OLinuXino/A13/A13-LCD7-TS/ https://www.olimex.com/Products/OLinuXino/A13/A13-LCD43TS Note that by the time of updating this manual the 10 inch display isn't still properly supported under all OLinuXino boards but it is relatively easy to add such support and once we have tested all configurations such images would be posted. 2.3 Powering the board There are two possible ways of powering A13-OLinuXino-MICRO – via external supply using the power jack, or via the USB OTG connector. Depending on your preferred way of powering A13- OLinuXino-MICRO you might need additional hardware. The preferred way of powering board is via the PWR jack with 5Vdc with a power of 5W (e.g. 5Vx1A ). This will make the board fully powered and able to power most peripherals connected to it. The board can also be powered by the USB OTG connector (mini USB standard) but the power provided by a standard USB is not enough to power a lot of peripherals - either a LCD (connected tothe LCD_con) or USB peripherals (connected to the USB type B) but not to power both. If you still wish to use USB power there are is the option to use adapter 2xUSB type A to 1xUSB type mini. If you have a standard LCD display connected to LCD_con, Android and WIFI running the typical consumption is around 450mA depending on the current load. While the board is in stand-by mode it consumes a minimum of 70mA. All the three approximate values above were taken when I applied 5V to the board. For the European customers we sell a power supply adapter 5V/0.5A – SY0605E. We also sell USB type A to USB mini cables if you lack such. The needed username/password combination for the Linux on the Olimex Linux distribution is root/password. Page 8 of 29 OLIMEX© 2012 A13-OLinuXino-MICRO user's manual 2.4 Prebuilt software Note that the A13-OLinuXino and A13-OLinuXino-MICRO lack NAND memory and WIFI and there isn't OS uploaded on the shipped boards. So far we have been successful in using Debian booting from SD card with both of the boards. The same can't be said for booting Android from SD card. 2.5 Software instructions and available SD card images This can vary depending on what the owner of the board want to achieve. Good collection on information on the subject can be found at the following WIKI articles: https://www.olimex.com/wiki/A13-OLinuXino-MICRO https://www.olimex.com/wiki/A13-OLinuXino Other good sources are: 1) the Wordpress site where a lot of side projects are published and explained: http://olimex.wordpress.com/?s=a13+micro 2) the Olimex forum in its A13 section https://www.olimex.com/forum/ Page 9 of 29 OLIMEX© 2012 A13-OLinuXino-MICRO user's manual CHAPTER 3: A13-OLinuXino-MICRO BOARD DESCRIPTION 3. Introduction to the chapter Here you get acquainted with the main parts of the board. Note the names used on the board might differ from the names used below to describe them.

Page 13 of 29 OLIMEX© 2012 A13-OLinuXino-MICRO user's manual CHAPTER 5: CONTROL CIRCUITY 5. Introduction to the chapter Here you can find information about reset circuit and quartz crystals locations, the power supply circuit is discussed. 5.1 Reset The reset line is handled by MCP130T-300-I. This is a voltage supervisory device designed to keep a microcontroller in reset until the system voltage has reached the proper level and stabilized. It also operates as protection from brown-out conditions when the supply voltage drops below a safe operating level. The reset goes to processor pin 195. The reset circuit is connected to button RESET, which means pressing RESET would perform a hardware reset on the board. 5.2 Clock 24 MHz quartz crystal Q1 is connected to pins 91 and 92 of the A13 processor. 5.3 Power supply circuit The 5V power supply is handled by three voltage regulators for the 1.2V, 1.5V and 3.3V power lines. The board can be powered from the USB_OTG connector. Note that powering from the USB limits the current available for peripheral devices (like mouse, keyboard, LCD display, UEXT modules, etc.). Page 14 of 29 OLIMEX© 2012 A13-OLinuXino-MICRO user's manual CHAPTER 6: CONNECTORS AND PINOUT 6. Introduction to the chapter In this chapter are presented the connectors that can be found on the board all together with their pinout and notes about them. Jumpers functions are described. Notes and info on specific peripherals are presented. Notes regarding the interfaces are given. 6.1 Communication with the A13 The chip has a built-in bootloader but the communication for this type of board is not very useful via the mini USB – the board lacks NAND. However, there is a second option which is the male UART1 connector capable of delivering some information on the COM port of your computer. You can use USB-SERIAL-CABLE-F with the UART1 interface allowing you to connect to an USB port. Note that we haven't still managed to run Android from the SD card so it might require tweaking the image to be able to do it. We have had a successful Debian booting from SD card. 6.1.1 USB communication There is only one USB type A host wired to a USB-controller. This means that an external USB hub is required to ensure you have enough room for all USB devices you might want to use (keyoard, mouse, etc). 6.1.2 UART1 interface The UART interface might be used for COM communication. You can use our USB-SERIAL- CABLE-F for debugging via the UART1 or UART0. Note that in both cases the connectors and the signals are named at the bottom of the board. Note that UART0 has only pinholes available, while UART1 has male connectors. Consider the below table when connecting the USB-SERIAL-CABLE-F according to the wire color code of the cable - GND=BLUE, RX(INPUT)=GREEN, TX(OUTPUT)=RED; note that RX of the cable has to connect to TX of the board and vice versa.

The SD card can be used for booting the operating system for A13-OLinuXino-MICRO. It is suggested to have an SD card with a proper Linux/Android image especially since you have ordered a board from the A13 family without built-in memory. We have tested a number of microSD cards on the OLinuXino boards and all of them worked fine regardless manufacturer or capacity. However, keep in mind that some of the lower quality microSD cards might draw too much current from the slot which might cause power-state problems. If you suspect the microSD card is causing problems please try using another one of better quality for better results. microSD card connector Pin # Signal Name Processor Pin # 1 DAT2/RES 113 2 SDC0_DATA3 112 3 SDC0_CMD 111 4 VDD - 5 SDC0_SCK 110 6 VSS - 7 SDC0_DATA0 108 8 SDC0_DATA1 107 Page 16 of 29 OLIMEX© 2012 A13-OLinuXino-MICRO user's manual When removing the card, please make sure that you release it from the connector by pushing and NOT by pulling the card directly (this can damage both the connector and the microSD card).

Page 28 of 29 OLIMEX© 2012 A13-OLinuXino-MICRO user's manual 8.4 Product support For product support, hardware information and error reports mail to: support@olimex.com. Note that we are primarily a hardware company and our software support is limited. Please consider reading the paragraph below about the warranty of Olimex products. Warranty and returns: Our boards have lifetime warranty against manufacturing defects and components. During development work it is not unlikely that you can burn your programmer or development board. This is normal, we also do development work and we have damaged A LOT of programmers and boards during our daily job so we know how it works. If our board/programmer has worked fine then stopped, please check if you didn't apply over voltage by mistake, or shorted something in your target board where the programmer was connected etc. Sometimes boards might get damaged by ESD shock voltage or if you spill coffee on them during your work when they are powered. Please note that warranty do not cover problems caused by improper use, shorts, over-voltages, ESD shock etc. If the board has warranty label it should be not broken. Broken labels void the warranty, same applies for boards modified by the customer, for instance soldering additional components or removing components - such boards will be not be a subject of our warranty. If you are positive that the problem is due to manufacturing defect or component you can return the board back to us for inspection. When we receive the board we will check and if the problem is caused due to our fault and we will repair/replace the faulty hardware free of charge, otherwise we can quote price of the repair. Note that all shipping back and forth have to be covered by the customer. Before you ship anything back you need to ask for RMA. When you ship back please attach to it your shipping address, phone, e-mail, RMA# and brief description of the problem. All boards should be sent back in antistatic package and well packed to prevent damages during the transport. Page 29 of 29
