A5x series module is a wireless data transmission terminal based on LoRa modulation and spread spectrum technology, which uses LoRa network to provide users with wireless data transmission function. The A5x series modules use high-performance industrial-grade LoRa solutions, support LoRaWAN1.0.2 standard protocol communication, support point-to-point communication, and provide IoT application functions such as peripheral control, power management, and data transmission.

A5x series modules are based on STM32 ultra-low power SoC chips, the core uses STMicroelectronics' STM32L4xx series, and the RF part uses Semtech's SX1262 long-distance, low-power wireless transceiver chip, suitable for various IoT application project node design.

A5x series modules have been widely used in M2M industries in the IoT industry chain, such as smart grid, smart transportation, smart home, finance, mobile POS terminals, supply chain automation, industrial automation, smart buildings, fire protection, public safety, environmental protection, meteorology, digital medicine, telemetry, military, space exploration, agriculture, forestry, water, coal, petrochemical.
