Product Description
LoRaWAN low-power RF module
Overview
Ai-Thinker Ra-07/Ra-07H module is a LoRaWAN module that supports long-distance communication, ultra-low power consumption, high sensitivity, and high cost performance. The chip ASR6501 of the module integrates a LoRa radio transceiver, a LoRa modem and a 32-bit RISC MCU. MCU uses ARM Cortex M0 + core, operating frequency is 48MHz. The operating frequency range of ASR6501 can support continuous coverage from 150MHz to 960MHz; it supports LoRa modulation and (G)FSK modulation.
