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.
The [RAK12500 GPS sensor](https://store.rakwireless.com/products/wisblock-gnss-location-module-rak12500) is a newer GPS module and is generally preferred.
- uBlox Zoe-M8Q GNSS receiver
- GPS, GLONASS, QZSS and BeiDou satellite support
The RAK12500 is supported on the following base boards & slots:
The [RAK1910 GPS sensor](https://store.rakwireless.com/collections/wisblock-sensor/products/rak1910-max-7q-gnss-location-sensor) is the older of the supported GPS modules for RAK boards.
The [RAK18001 Buzzer Module](https://store.rakwireless.com/products/wisblock-buzzer-module-rak18001) 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.
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.
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.
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:
The [RAK1901 Temperature and Humidity Sensor](https://store.rakwireless.com/products/rak1901-shtc3-temperature-humidity-sensor) is based on the Sensirion SHTC3 module and has the following features:
- Temperature measurement (Range -40°C to +125°C)
The [RAK1902 Barometric Pressure Sensor](https://store.rakwireless.com/products/rak1902-kps22hb-barometric-pressure-sensor) is based on the STMicroelectronics LPS22HB module and has the following features:
The [RAK1906 Environment Sensor](https://store.rakwireless.com/products/rak1906-bme680-environment-sensor) is based on the Bosch BME680 module and has the following features:
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.
