This Framework laptop expansion card will show up on your system as a serial device and allow for a serial RS-232 communication up to 115,200 baud rate.
| # | Ref | Description |
|---|---|---|
| 1 | RXD | Receive (RS-232) |
| 2 | GND | Ground connection |
| 3 | TXD | Transmit (RS-232) |
PS: Colors are just a suggestion and it's not necessary to have them match the table.
To connect to this board, one has to use 3-pin JST XH connector. The following table represents the pinout, pin 1 being on the left as looking into the expansion card.
As power consumption is below 10 mA, wires can be almost any AWG. I would recommend using 24 AWG wire 0.25 mm² as they allow for greater compatibility with other connectors.
