Ricros built a free MCP2200 breakout board. MCP2200s are USB-to-UART converter chips from Microchip. They are actually a remarked PIC18F14K50 microcontroller programmed with the USB-to-UART firmware – we were able to hack one and reprogram it to run an open source USB stack.
If you build a free PCB we’ll send you another one! Blog about it, post a picture on Flicker, whatever – we’ll send you a coupon code for the free PCB drawer.
