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.

The SV1 connector is designed to be connected to the 40 pin expansion connector of Terasic FPGA boards. This can be done with a standard 40 pin IDE cable, provided that it isn't too long.

40-pin connector SV1 is connected as follows:
