This is the documentation page for the FTDI-serial board.


The FTDI-serial board has an USB connector and a 3-pin serial/UART connector. The brains of the PCB is an FT232RL chip.

External resources


The 3 pin connector is connected as follows

1Ground (G)
2Rx (R)
3Tx (T)works at 5V or 3.3V level depening on jumper
4V+5V or 3.3V depending on jumper
  • led1 is connected to CBUS0 (Tx activity)
  • led2 is connected to BCUS1 (Rx activity)
  • led3 is connected to VCC

Jumper settings

IO voltage
1-2: 3V3 (jumper near C2)
2-3: 5V (jumper near the edge of the board

future hardware enhancements



  • Size reduced considerably
  • Added an VCC pin to the Rx/Tx connector


  • Initial public release
