Ai-Thinker RA-08 LoRa Module

Description-

The Ra-08 is a LoRa module crafted by Shenzhen Ai-Thinker Technology Co., Ltd., designed for ultra-long-distance spread spectrum communication. It features the ASR6601 chip, a versatile LPWAN wireless communication SOC that integrates RF transceivers, modems, and a 32-bit RISC MCU. This MCU utilizes an ARM core operating at a frequency of 48MHz. The Ra-08 module accommodates LoRa modulation and conventional (G)FSK modulation within the LPWAN framework. Additionally, the transmitter is capable of BPSK modulation and (G)MSK modulation, while the receiver also supports (G)MSK modulation. Offering long-range and ultra-low power consumption, the Ra-08 module is ideal for LPWAN applications across various sectors, including smart meters, supply chain and logistics, home and building automation, security systems, and remote irrigation systems.
