RAK4631 - nRF52

:::info Please be aware of the difference between the RAK4631 (Arduino bootloader) and the RAK4631-R (RUI3 bootloader). Meshtastic requires the Arduino bootloader. If you have a RAK4631-R, please see the instructions for converting the bootloader. :::

RAK4631 Core Module

GPIO

:::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. :::

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 to toggle power to peripheral modules using 3v3_S power rail, not available for user application
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

RAK11310 - RP2040
