Product Descriptions
Ra-08H-Kit is a LORaWAN development board that is equipped with a LoRa module and comes with serial and peripheral pins. With the factory firmware, it can easily control the transmission and reception of LORaWAN by connecting to the serial assistant and sending commands;
The ASR6601 chip is a universal LPWAN wireless communication SoC that integrates an RF transceiver, modem, and a 32-bit RISCUMC. This MCU uses an ARM core and can operate at a frequency of up to 48MHz;
The Ra-08 module supports LoRa modulation and traditional (G) FSK modulation for LPWAN use cases; The transmitter also supports BPSK modulation and (G) MSK modulation, while the receiver supports (G) MSK modulation;
The Ra-08 module on the development board provides ultra long range and ultra-low power communication for LPWAN applications, which can be widely used in scenarios such as smart meters, supply chain and logistics, home building automation, security systems, remote irrigation systems, etc.
