Product Description The module is available in two variants: RAK4631-R is for low power application designed with RUI3

RAK4631 is for use with the Arduino IDE BSP

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
