FT230X Serial Board

This is a small board for breaking out the pins of the FT230X with a USB-C connector. It was designed in KiCad version 5.1.6 on macOS 10.15 Catalina and the full project is available on the GitHub repository.

Features

  • USB-C connector with ESD protection chip
  • Polyfuse on VUSB power rail
  • 2.54 mm spaced headers for breadboard compatibility
  • All pins of FT230X available on the headers
  • Jumpers on the bottom of the board to select between different voltages and self vs bus powered mode
  • LEDs for VCC and VIO
  • LEDs for TX and RX activity (must program the FT230X CBUS pins for these LEDs to work)
  • 4 layer board (can be redesigned for 2 layers, but due to the small size the price difference is negligible)
