Disassembly
- Remove the two screws hidden under the rubber feet on the back of the unit
- Use a plastic pry tool to separate the rear cover, as it is held in place by a snap fit
Note Be careful when prying the rear cover off, the snap fit clips can break easily.
Serial
The board has GND, TX and RX headers already soldered. A USB UART adapter such as a CH340G can be used to access the serial console.
| USB TTL(UART) Adapter | Board header |
|---|---|
| GND | GND |
| TX | RX |
| RX | TX |
Note Some USB TTL adapters label TX and RX pins the other way around: try to swap them if the connection doesn’t work.
