Open Source FTDI FT2232 JTAG and UART Adapter board

Learn more about the open-source FTDI FT 2232 JTAG and UART adapter board.

In JTAG Debugging the ESP32 with FT2232 and OpenOCD, I used an FTDI FT2232 breakout board to JTAG debug with OpenOCD. With an adapter board on top of the TDI FT2232, the wiring is much easier and simpler to use:

The wiring includes a JTAG header with pull-up and pull-down, plus a UART header:

The board hooks on the FTDI breakout board and makes a debug and UART connection to the target board:

The KiCAD project and files are available on the GitHub site noted in the following links section.

Happy Debugging!
