RAK WisBlock LPWAN Module RAK4631 (Ardunio/EU868)

The RAK4631 WisBlock LPWAN is a WisBlock Core module which delivers a powerful Nordic nRF52840 MCU with BLE 5.0 paired to the latest LoRa® transceivers from Semtech, the SX126x series.

Compared to the older SX127x series the Semtech SX126x transceivers offer improved power consumption and the improved power amplifier can now transmit at up to +22dBm, with a total link budget up to 170dB for extended communication range. This makes the RAK4631 our best ever long range capable, ultra-low-power communication solution.

Designed for global deployment, the RAK4631 WisBlock Core comes in two variants, RAK4631(H) supporting ISM bands from 779-923MHz, including those typically used in Europe, USA, India, and the RAK4631(L) variant for the 433-470Mhz bands aimed at China and 433Mhz specific deployments.

The module also includes a temperature-controlled crystal oscillator (TXCO) for correct operation across a wide range of temperature and bandwidth requirements as well as multiple communication interfaces including UARTs, I2C, SPI, ADC, USB and GPIOs.

RAK4631 together with one of our WisBlock Base modules can be easily expanded with many available sensors and IO boards. This is the ideal LoRa® end node for battery and/or solar-powered applications in remote locations.

The Arduino version can be easily programmed with the Arduino IDE or the PlatformIO extension for IDE’s like Atom, MS Visual Studio Code, or Clion using our Arduino BSP. Please check our RAK4631 documentation.

The RUI3 version can be easily programmed with the Arduino IDE or Visual Studio using our RUI3 Arduino BSP. Please check our RAK4631-R documentation.

The Arduino and Voice Processing versions can be used with WisBlock Audio. The Voice Processing version includes a Cyberon License. Please check our Comparison Table for more information.
