RAK3372 WisBlock LPWAN Module

Thank you for choosing RAK3372 WisBlock LPWAN Module in your awesome IoT project! 🎉 To help you get started, we have provided you with all the necessary documentation for your product.

Product Description​

The RAK3372 WisBlock Core module is based on RAK3172 LoRa module with an expansion PCB and connectors compatible with WisBlock Base. It allows an easy way to access the pins of the RAK3172 module to simplify development and testing processes.

The module itself comprises RAK3172 as its main component. The RAK3372 is based on the STM32WLE5CCU6 LoRa SoC transceiver chip. It features ultra-low power consumption of less than 2.0 uA during sleep mode with configurable high LoRa output RF power up to 22 dBm during transmission mode. Also, it complies with LoRaWAN 1.0.3 protocols and supports LoRa point-to-point communication.

warning

Prerequisites​

To use a RAK3372, you need at least a WisBlock Base to plug the module in. WisBlock Base is the power supply for the RAK3372 module and has the programming/debug interface.

warning
  • When using the LoRa transceiver, make sure that it is connected to an antenna. Using the transceiver chip without an antenna can damage the system.
  • Make sure to fix the module with screws to ensure proper function.
