Ra-07H Product Specification

Introduction:

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 LoRa radio transceiver, LoRa modem and 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;

Support LoRa modulation method and (G)FSK modulation method.

Characteristic:

With super anti-interference ability, it can work normally in complex interference environment

Minimum receiving sensitivity: -137dBm (SF=12/BW=125KHz)

Maximum transmit power +21dBm

Working frequency: 803MHz~930MHz (default)

Power supply voltage input: 3.3V

Transmitting working current: 107mA (full load power consumption)

Receiving working current: 6mA

Sleep current: 3uA

Gateway

LoRa private concentrator protocol, flexible, simple, and customizable

Node modules in the area are automatically added to the gateway to form a star network, and three working modes of Class A/Class B/Class C can be selected to join the gateway

LoRA gateway three-channel communication, three working frequencies can be configured, and three channels of data can be sent and received at the same time

Support WAN port, support WIFI, optional 4G module

Support MQTT protocol to connect to cloud server, open MQTT protocol interface

Long-distance transmission, the transmission distance can reach 3000 meters under the open outdoor

Using MediaTek processor MT7688, main frequency: 580MHz, 128Mb Flash, 512Mb RAM
