FT2232H breakout board

This is the documentation page for the FT2232H breakout board.

overview

The FT2232H breakout board has an USB connector, two 20-pin HDR-standard IO connectors (one for BUS0 and one for BUS1), and one 40-pin terasic compatible connector. The brains of the PCB, of course, is an FT2232H chip.
