## RAK GPIO Pin Mapping
|
|
|
|
The RAK4631 uses symbolic labels for its I/O Pins on the module and baseboard silk screens. The following table shows the mapping of the RAK4631 GPIO pins to the corresponding Arduino pins and the MCU Port numbers.
|
|
|
|
| RAK Pin | nRF52840 Pin | Arduino GPIO | Remark |
|
|
| ------- | ------------ | ------------ | ------------------------------------------------------------------------ |
|
|
| IO1 | P0.17 | 17 | used for GPS PPM signal if GPS module is connected |
|
|
| IO2 | P1.02 | 34 | used to power all peripheral modules, not available for user application |
|
|
| IO3 | P0.21 | 21 |
|
|
| IO4 | P0.04 | 4 |
|
|
| IO5 | P0.09 | 9 | The 'User Button' is mapped here. |
|
|
| IO6 | P0.10 | 10 |
|
|
| IO7 | P0.28 | 28 |
|
|
| SW1 | P0.01 | 1 |
|
|
| A0 | P0.04/AIN2 | A2 |
|
|
| A1 | P0.31/AIN7 | A7 |
|
|
| SPI_CS | P0.26 | 26 |
|
|
|
|
When configuring GPIO pins in your device settings, the Arduino GPIO numbers should be used.
|
|
|
|
```shell title="Example"
|
|
meshtastic --set external_notification.output 10
|
|
```
|
|
|
|
This will use IO6 on a RAK4631
|
|
|
|
:::caution Note
|
|
There is no usable GPIO pin on any RAK base board except the 'big' baseboard RAK19001 without adding a RAK13002 IO module or a third party IO sensor breakout.
