AI-Thinker Ra-08 (750-Reel) bit-kit It improves the transducer's corrosionRa 08 is an LoRa module designed and developed by Shenzhen Ai Thinker Technology Co., Ltd. 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
