Supported Peripherals

GPS Module

To add a GPS to the RAK5005-O base board, you need the RAK1910 GPS sensor. It is supported on slot A of the 5005 board via UART.

• uBlox MAX-7Q GPS module
• GPS and GLONASS satellite support

Further information on the RAK1910 can be found on the RAK Documentation Center.

To add a GPS to the RAK19003 base board, you need the RAK12500 GPS sensor. It is supported via I²C on slot B for firmware versions 1.49 and above.

• uBlox Zoe-M8Q GNSS receiver
• GPS, GLONASS, QZSS and BeiDou satellite support

Further information on the RAK12500 can be found on the RAK Documentation Center.

Buzzer

The RAK18001 Buzzer Module is currently being tested for integration with the External Notifications plugin. There is currently a known conflict with buzzer if the module is placed in Slot D, although other slots should work.

Further information on the RAK18001 can be found on the RAK Documentation Center.

I/O 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.
Further information on the RAK13002 can be found on the RAK Documentation Center.
