RAK WisBlock Supported Peripherals
- User Button
- GPS Module
- Buzzer
- Vibration
- I/O Module
- Environmental Sensors
- RTC Module
User Button
Any tactile momemtary push button is compatible as long as it is wired to the correct pins, here's a sample of a Push Button
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
- 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.

Buzzer
RAK Buzzer
The RAK18001 Buzzer Module may be used with the External Notifications plugin. There is currently a known conflict with the buzzer if the module is placed in Slot D, although other slots should work. NOTE: Many users have complained of the RAK buzzer being very quiet as currently implemented. As of yet, there is no fix for this issue.

Third Party Buzzer
Another option is to use a standard "passive buzzer" and a transistor (such as a 2N2222 transistor). This can be done by wiring the VCC pin to leg 1 of the transistor and the positive terminal of the buzzer to leg 3. To the central pin (2) of the transistor, connect pin RX1 on the Wisblock board. Connect the negative terminal of the buzzer to the GND pin on the Wisblock board. In settings, go to Device and set Redefine PIN_BUZZER (Buzzer GPIO) to 15. Then go to External Notification and set the module to Enabled, PWM buzzer to enabled, Alert Message Buzzer to enabled and Output Buzzer GPIO to 15. Save your settings and your buzzer should activate whenever you get an incoming message.

Vibration
To add vibration to your Wisblock device you'll need a standard 3V DC vibramotor and a transistor (such as a 2N2222 transistor). This can be done by wiring the VCC pin to leg 1 of the transistor and the positive (red) wire of the vibramotor to leg 3. To the central pin (2) of the transistor, connect pin AIN1 on the Wisblock board. Connect the negative wire (black) of the vibramotor to the GND pin on the Wisblock board. In settings, go to External Notification and set the module to Enabled, Alert Message Vibra to enabled and Output Vibra GPIO to 31. Save your settings and vibration should activate whenever you get an incoming message.

IO Module
The RAK13002 IO Module 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 I2C 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.

RAK1901 Temperature and Humidity Sensor
The RAK1901 Temperature and Humidity Sensor is based on the Sensirion SHTC3 module and has the following features:
- Temperature measurement (Range -40°C to +125°C)
- Humidity measurement (Range 0% to 100%)
- Lower power consumption
RAK-1902 Barometric Pressure Sensor
The RAK1902 Barometric Pressure Sensor is based on the STMicroelectronics LPS22HB module and has the following features:
- Barometer measurement (Range 260 to 1260 hPa)
- Low power consumption of 3uA
- Small form factor
RAK1906 Environment Sensor
The RAK1906 Environment Sensor is based on the Bosch BME680 module and has the following features:
- Temperature measurement (Range -40°C to +85°C)
- Humidity measurement (Range 0% to 100%)
- Barometer measurement (Range 300 to 1100 hPa)
- Air Quality measurement

RTC Module
The RAK12002 WisBlock RTC Module 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.
