Check base-board slots, pin assignments, interfaces and RAK3312 firmware examples when combining modules.

 

Antenna Cables & Adapters

LoRa and Wi-Fi/BLE antennas are included. For an external antenna, choose an MHF-4* module-side connector and the correct connector at the antenna end.

• MHF-4 to N-Type Female RF Cable – 200mm - for a suitable external LoRa antenna with an N-Type male connector

Use an EU868 antenna for LoRa and a 2.4GHz antenna for Wi-Fi/BLE.

*The RAK3312 uses MHF-4 antenna connectors. MHF-1 cables used with the RAK4631 do not fit this module.

 

Power Your Build

RAK3312 or RAK4631?

 

Choose this RAK3312 if you’re building a device that combines long-range LoRa with local Wi-Fi or BLE - such as a sensor with a Wi-Fi setup page, connected display or more demanding data processing.

 

Choose the RAK4631 Arduino EU868 if you’re building a battery-powered LoRa/BLE sensor, tracker or remote monitoring device and want to write your own application using Arduino or PlatformIO.

 

Choose the RAK4631-R RUI3 EU868 if you want ready-supplied firmware for configuring the radio and sending data through AT commands - for example, from another controller - or prefer developing your application with RAK’s RUI3 APIs.

 

Firmware and pin assignments differ between Cores. Check examples and libraries before changing your project’s Core module.
