Hi, I wanted to share my design of a Stellaris ARM Cortex-M3 MCU board.
I've managed to make it so it can be used with either LM3S3748 (USB device/host) or LM3S6938 (Ethernet).
I've had it manufactured by iTead studio, and I think the result is perfect, no problems at all.
I like Stellaris chips because you can get them as free samples from TI :), they have a great C library (StellarisWare) with lots of examples, and you can program for them using only GCC and OpenOCD.
