## User Button

Any tactile momemtary push button is compatible as long as wired to the correct pins, here's a sample of a [Push Button](https://a.co/d/bPhhTxm) 


The button is recommended to be used on the following base board's exposed pins or slots :

- RAK19007 on AIN1 (Pin 31) - See supporting instructions [Here](https://store.rokland.com/pages/adding-a-user-button-rak19007)
- RAK19001 on IO5 (Pin 37)

## Wiring
One side of the switch should be on GND and the other on the recommended Pin per your baseboard. The pin must be configured on the node using the app, webclient or CLI.

## IO Module

The [RAK13002 IO Module](https://store.rakwireless.com/collections/wisblock-interface/products/adapter-module-rak13002) can be used to, among other things, add a user button to the RAK base boards (excluding the RAK19003 Mini base board). It features a number of different interface options:

- 2x I<sup>2</sup>C interfaces
- 2x UART interfaces
- 1x SPI interface
- Upto 6x GPIOs
- 2x ADC interfaces
- 3.3v Power rails

There is development activity in progress to get sensors such as this added to the Meshtastic Core.

<TabItem value="RTC">

## RTC Module

The [RAK12002 WisBlock RTC Module](https://store.rakwireless.com/products/rtc-module-rak12002) is a real-time-clock with a supercapacitor backup, allowing a node to maintain the correct time across reboots and for up to seven days without power. It operates on a crystal oscilator and communicates via the i2c interface. The module can be inserted into slots A, B or C (some users have reported issues with slot D) and is plug and play - no settings are required.
