AI-Thinker Ra-08-Kit Development Board

Ra-08-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 to serial ports and peripheral pins, which can be connected to the factory firmware through the The serial port 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-08 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-08 module on the development board provides ultra-long range and ultra-lowpower communication for LPWAN applications, which can be widely used in smart meters, supply chain and logistics, home building a tomation, security systems, remote irrigation systems and other scenarios.
