Ra-08H-Kit (915MHz) Development Board

Ra-08H-Kit is a LoRaWAN development board designed and developed by Shenzhen Ai-Thinker Technology Co., Ltd. The development board is equipped with a LoRa module, and leads out the serial port and peripheral pins, which can be connected to the serial port with the factory firmware. The assistant can easily send and receive LoRaWAN control by sending commands. The chip ASR6601 on the development board is a general-purpose LPWAN wireless communication SoC that integrates an RF transceiver, a modem and a 32-bit RISCMCU. The MCU adopts ARM core, and the operating frequency can reach 48MHz. The Ra-08H module supports LoRa modulation and traditional (G)FSK modulation under the LPWAN use case; at the same time, the transmitter also supports BPSK modulation and (G)MSK modulation, andthe receiver supports (G)MSK modulation. The Ra-08H module on the development board provides ultra-long range and ultra-low power communication for LPWAN applications, which can be widely used in smart meters, supplychain and logistics, home building automation, security systems, remote irrigation systems andother scenarios.
