Overview

This project contains open hardware design files for an experimental adapter board based on FTDI FT2232H/FT4232H IC. The board exposes the programmable IO buses from the FT2232H/FT4232H on a 2.54 mm goldpin header, allowing the implementation of many popular IO interfaces which are useful during hardware debugging. Those interfaces include:

• UART - two independent channels with optional flow control and selectable IO voltage (5.0V, 3.3V, 1.8V)
• I2C bus initiator with selectable IO voltage standard (5.0V, 3.3V, 1.8V)
• SPI bus initiator with selectable IO voltage standard (5.0V, 3.3V, 1.8V)
• JTAG openocd-compliant with selectable IO voltage standard (5.0V, 3.3V, 1.8V) and fixed 3.3V IO voltage standard
• SWD openocd-compliant with selectable IO voltage standard (5.0V, 3.3V, 1.8V) and fixed 3.3V IO voltage standard

The design files were prepared in KiCad 7.
