Guan Yang draws our attention to a new member of the FT232 family, the FT231X.
I wanted access to more pins than your typical FTDI board provides, and realized that our friends at FTDI have designed a replacement for the venerable FT232 series that found a home in classical Arduinos, Bus Pirates and countless USB-to-serial boards. The FT231X is much cheaper and has cool new features like USB battery charger detection. There’s also a cheaper FT230X version that only has RX/TX, no flow control or GPIO pins.
I designed a breakout board for the chip in KiCad and put the board, schematic and Gerber files up on the Hack Manhattan wiki. This board breaks out every flow control and GPIO pin. A future update will make it easier to switch to 5V for VCC and I might also adopt the DP6037 form factor.
