FT2232H breakout board

This is the documentation page for the FT2232H breakout board.

Overview

The FT2232H breakout board has an USB connector, two 6 pin SPI connectors, two 4 pin I2C connectors and a general purpose connector. Besides that there are two jumpers for enabling the I2C ports, and a selector jumper that allows you to chose between 3.3V or 5V on the IO connectors.

Pinout

For the SPI connector pinout please see: SPI_connector_pinout

for the I2C connector pinout please see: I2C_connector_pinout

The general purpose connector J1 is:

GND	1	2	VCC
ACBUS0	3	4	ACBUS1
ACBUS2	5	6	ACBUS3
ACBUS4	7	8	ACBUS5
ACBUS6	9	10	ACBUS7

LEDS

• pwr is connected tot the 3.3V of the board.

If the led doesn't light when you expect it to be, then there is something seriously wrong. (or you need to plug it in).
