Product Summary

WisBlock Core is the processing unit of your IoT Solution.

Editorial narrative

WisBlock Core is the processing unit of your IoT Solution. Select a module matching the requirements of your application. Available modules include low-power single-core MCUs and fast dual-core MCUs. Different WisBlock Core modules offer different communication possibilities like LoRa®, Wi-Fi, BLE, and/or Bluetooth. The WisBlock Core modules 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. RAK4631 WisBlock LPWAN Core Module Available in three variants: For low-power applications designed with RUI3 - The RUI3 version can be easily programmed with the Arduino IDE or Visual Studio using our RUI3 Arduino BSP. For use with the Arduino IDE BSP and Meshtastic - The Arduino version can be easily programmed with the Arduino IDE or the PlatformIO extension for IDEs like Atom, MS Visual Studio Code, or Clion using our Arduino BSP. The RAK4631 is a WisBlock Core module that features a powerful Nordic nRF52840 MCU with BLE 5.0 paired to the latest LoRa® transceivers from Semtech , the SX126x series. It offers improved power consumption and the improved power amplifier can now transmit at up to +22dBm, with a total link budget of up to 170dB for an extended communication range. This makes RAK4631 our best long-range capable, ultra-low-power communication solution. Designed for global deployment, covering most used frequencies, 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. RAK11310 WisBlock LPWAN Core Module The RAK11310 module is based on the Raspberry Pi RP2040 MCU chip. We added the Semtech SX1262 LoRa® transceiver chip to open the world of LoRa® and LoRaWAN® connectivity to this module. Even though this module ha
