LoRa611Pro-100mW MESH LoRa Wireless Transceiver Data Transmission Module

LoRa611Pro is a wireless transceiver data transmission module, based on SX1276/1278 chips from Semtech. This module adopts LoRa technology to achieve high effective sensitivity and superior anti-interference. The communication distance and receiver sensitivity are far exceeds the FSK, GFSK modulation. For better security, the module uses AES128 encryption. LoRa611Pro has 100mW output power and TTL/RS232/RS485 interface available. It is widely applied in meter reading, remote industrial control, etc.

Application circuit


1) Power on Reset

Standard supply voltage of 5V (ordinary lithium battery of 4.2V is also applicable),After powered on reset, the TX LED (Red) and RX LED (Blue) will blink 3 times,(If no lights, module may damaged),The total reset time is around 2s.

2) Working Mode

The CS and SET Pin is internally pulled up. Pull CS pin high or leave it open will make the module enter into working mode.

In working mode, LoRa611 stay in receiving mode and wait for the series signal and RF signal.

Module can connect with any device which is standard TTL/RS232/RS485 interface.

When series signal comes, module will check the input series signal if there is any error, and then transmit the received data out via RF automatically if no errors found.

When RF signal comes, module will check the input RF signals if there is any error, and then transmit the received data out via series port automatically if no errors found.

When one packet is transmitted successfully, the Red LED will blink once.

When one packet is received and verified with no problem, the Blue LED will blink once.

The upgraded LoraPro series can be compatible with all versions of our LORA data before. The user can use PC software to configure the module to work mode according to his application needs. Now the comparison between several versions is as follows:

Ø Normal mode PC settings——( Work Mode = Normal + disable Encryption )

Ø AES mode PC settings——( Work Mode = Normal + Enable Encryption )

Ø MESH mode PC settings——( Work Mode = MESH ;Mode = Router or Node)

When set as ROUTER, in working mode, the module can repeat the RF signal in the same network automatically to extend the distance.

Normally, Router module is connected with external power supply to keep long time in receiving mode and repeat the signal to extend the range.

3) Setting mode

In working mode, pull low the SET pin to force the module into setting mode. When using USB

bridge board, simply put on the short cap to enter into setting mode.
