LoRa Module STM32WL Series – 868 MHz / 915 MHz (MOD31xx by Macnman Technologies)
The MOD31xx LoRa Module from Macnman Technologies Pvt. Ltd. is a compact, ultra-low-power wireless communication module based on the STM32WL Series microcontroller, designed for long-range and low-power IoT applications. This high-performance LoRa module integrates a sub-GHz transceiver with a built-in LoRaWAN protocol stack, providing secure, scalable, and energy-efficient connectivity for wide-area networks. Engineered for reliability and flexibility, the MOD31xx supports global license-free ISM frequency bands (868 MHz / 915 MHz), enabling worldwide deployment across various IoT applications. With exceptional sensitivity (-148 dBm) and an adjustable transmit power up to 23 dBm, this module ensures robust and long-distance communication — maintaining stable data transmission even in challenging environments.
Its versatile modulation capabilities including LoRa, FSK, GFSK, and OOK, allow for flexible communication setups such as LoRaWAN and point-to-point (P2P) modes with OTAA and ABP activation. Thanks to its ultra-low standby current (2.1 uA) and in-air wake-up functionality, the MOD31xx is optimized for battery-powered IoT nodes requiring years of operation without maintenance. Ideal for smart agriculture, utility metering, environmental monitoring, infrastructure control, and industrial automation, this module empowers developers to build reliable, future-ready IoT solutions with minimal effort and maximum range.
