This is the documentation page for the FTDI-serial board.
overview
The FTDI-serial board has an USB connector and a 4-pin serial/UART connector. The brains of the PCB is an FT232RL chip.
For references to left-right, and top-bottom in this page, please hold the board with the USB connector on the left and the serial connector on the right.

pinout
The 4 pin connector is connected as follows
| 1 | Ground (G) | |
| 2 | Rx (R) | do not drive at 5V level if jumper is set to 3.3v. probably works if driven at 3.3V with jumper at 5V. |
| 3 | Tx (T) | works at 5V or 3.3V level depening on jumper |
| 4 | V+ | 5V or 3.3V depending on jumper |
- led1 is connected to CBUS0 (Tx activity)
- led2 is connected to CBUS1 (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
