RAK4200 STM32L071 SX1276 Module for LoRaWAN
Prefer another courier for your delivery? Contact us for special shipping arrangements.
Product Description
RAK4200 LPWAN Module includes an STM32L071 MCU and an SX1276 LoRa® chip. It has an ultra-low power consumption of 1.5uA in sleep mode and high LoRa® output power up to 19dBm max in work mode.
The module complies with LoRaWAN® 1.0.2 protocols. It also supports Lora® Point-to-Point communications. The module is suitable for various applications that require long-range data acquisition and low power consumption.
Complete documentation of this product can be found on our website documentation page.
You can find a comparison table of our LPWAN modules here.
Note:
In order to have an optimal antenna matching for the Low and High LoRa bands, there are two types of modules with different hardware. The L type module only works for the 433MHz and 470MHz LoRa bands. The H type module is for the 868MHz to 923MHz (the rest of the spectrum). Note that the hardware is specific for your selected band and can't be changed.
