1. Product overview
The Ra-07H LoRaWAN module feature the Lora long range modem that provides ultra-long
range communication , Ultra low power and high interference immunity whilst minimising
current consumptio. The ASR6501 chip Integrated LoRa radio transceiver, LoRa modem and
32-bit RISC MCU. The MCU uses ARM Cortex M0 + core and operates at 48MHz. The
working frequency range of ASR6501 can support continuous coverage of 150MHz ~ 960MHz;
support LoRa modulation mode and (G) FSK modulation mode.
The ASR6501 supports ultra-high sensitivity and a maximum transmit power of + 21dBm. It is
suitable for long-distance LPWAN communication and has high transmission efficiency.
