Product Description

The RAK4631 WisBlock LPWAN is a WisBlock Core module that 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 an 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, the 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 the RAK5005-O WisBlock Base module 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. It can be easily programmed with the Arduino IDE or the PlatformIO extension for IDE's like Atom, MS Visual Studio Code, or Clion.
