Megabug built a free MCP2200 breakout board. MCP2200 are USB-to-UART converter chips by Microchip. In fact they are PIC18F14K50 microcontrollers programmed with the USB-to-UART firmware. We were able to hack one and program an open source USB stack into it.
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.
