386EX PC/104 Computer with CompactFlash and PCMCIA SBC1390 Features Small, low cost, ready to run 386EX, 25 or 33MHz Up to 32MB DRAM CompactFlash connector Optional PC Card interface for Wi-Fi, modem, Ethernet, and other I/O Four serial ports Extended temperature range available The SBC1390 packs a fast 386EX processor storage capacity is required, the CompactFlash with plenty of memory, and copious amounts of connector allows hundreds of megabytes of storage into a PC/104-sized board. The optional removable program and data storage. PC Card interface allows many different types of I/O to be added. Wi-Fi (802.11b) cards, modems, Four serial ports, five digital I/O lines, three or Ethernet interfaces can be plugged into the counter/timers, and a watchdog timer mean that PC Card slot. the SBC1390 won’t require any additional I/O for many applications. However, if additional With 1MB of on-board flash, accessible as a capabilities are needed, PC/104 expansion allows read/write disk, and up to 32MB of DRAM, many a wide variety of I/O cards to be stacked on the large programs can be run.
