Ra-08 is an LoRa module designed and developed by Shenzhen Ai-Thinker TechnologyCo., Ltd. The module is used for ultra-long distance spread spectrum communications. Its chipASR6601 is a universal LPWAN wireless communication SOC, integrated with RFtransceivers, modems, and a 32-bit RISC MCU. The MCU adopts an ARMcore 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 BPSKmodulation and (G) MSK modulation, receiver support (G) MSK modulation. The Ra-08 module provides long-range and ultra-low power communications for LPWANapplications, which can be widely used in smart meters, supply chain and logistics, homebuilding automation, security system, remote irrigation system and other scenes.
