RAK3172 STM32WLE5 Module for LoRaWAN
Prefer another courier for your delivery? Contact us for special shipping arrangements.
RAK3172 is a low-power long-range transceiver module for LoRa and LoRaWAN applications based on the STM32WLE5CC chip. Its firmware is based on RAKwireless Unified Interface V3 (RUI3) which allows you to create different functionalities using RUI APIs. It provides an easy-to-use, small-size, low-power solution for long-range wireless data applications. This module complies with Class A, B, & C of LoRaWAN 1.0.3 specifications. It can easily connect to different LoRaWAN server platforms like TheThingsNetwork (TTN), Chirpstack, Helium, etc. It also supports LoRa Point-to-Point (P2P) communication mode which helps you in implementing your own customized long-range LoRa network quickly.
It can work as a standalone device by creating custom firmware via RUI3 APIs or can be deployed as a LoRA modem with an external host like a microcontroller or microprocessor that configures and sends commands to the module using AT and Binary commands via a UART interface.
The RAK3172 is available in variants with TCXO to assure higher clock precision in low temperature conditions and with an oscillator for normal environment conditions.
Note:
- The antenna of Check to Include is a supporting antenna for certification.
- When purchasing Blade Antenna, you need to use it with IPEX TO RP-SMA Connector.
- As our customers are starting mass-production and deploying their products globally, we want to clarify that our modules hardware is supporting multiple LoRaWAN regions. As there is no difference in the hardware, we optimized the variants in our store to make it easier to select the correct module. Please note that the difference between the variants is only in the label on the module to reflect the different regional telecommunication certifications.
