Description:

Ra-08 is a LoRa module designed and developed by Ai-Thinker. The RA-08H LoRa Module is used for ultra-long distance spread spectrum communications. RA-08H LoRa Module 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; the receiver supports (G) MSK modulation.

The RA-08H LoRa Module provides long-range and ultra-low power communications for LPWAN applications, which can be widely used in smart meters, supply chain and logistics, homebuilding automation, security systems, remote irrigation systems and other scenes.
