Any robot hobbyist can tell you about the difficulties of working with the high-density connectors and surface mount technologies common on most modern microcontroller chips. Tin Can Tools designed the Hammer as an answer to that problem. The Hammer is a single board computer designed on a DIP style 40 pin module with 0.1 inch pins, making it easy to use in homebrew projects built on perf boards. The SBC is based on a Samsung S3C2410A SoC which includes an ARM920T (with MMU) running at 200MHz. I/O includes 2 UARTS with IrDA support, I2C interface, 2 SPI ports, 2 16bit timer/PWMs, an 8bit LCD interface, USB host and device ports, 2 10bit ADCs, 4 external interrupt pins, JTAG, and up to 30 pins of GPIO. The only catch is that you're limited to 40 physical pins on the modules, so you can't use everything at the same time. Tin Can Tools also offers an optional carrier board and JTAG programmer. The JTAG programmer, called Flyswatter, works with any ARM processor supported by the OpenOCD On-Chip-Debugger. For more see the LinuxDevices.com story
