Ai Thinker LoRa Series Ra-08H Spread Spectrum Wireless Module

The module is used for ultra-long distance spread spectrum communications. Its chip ASR6601 is a universal LPWAN wireless communication SOC, integrated with RF transceivers, modems, and a 32-bit RISC MCU. The MCU adopts an ARM core with a working frequency of 48MHz. The Ra-08 module supports LoRa modulation and traditional (G)FSK modulation under the LPWAN. At the same time, the transmitter also supports BPSK modulation and (G) MSK modulation, receiver support (G) MSK modulation. The Ra-08 module provides long-range and ultra-low power communications for LPWAN applications, which can be widely used in smart meters, supply chain and logistics, home building automation, security system, remote irrigation system and other scenes.
