LoRa611 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. With superior anti-interference. Lora611 has 100mW output power and TTL/RS232/RS485 interface available. It is widely applied in meter reading, remote industrial control, etc
Transmission distance in open area up to 5000 meters @ 91bps
Sensitivity: -139 dBm
Max output power: 100mW（+20dBm）
Working voltage: 3.3 ~ 6.5 V
Working temperature: -40 ~ +85 °C
Remote control telemetry
Remote meter reading
Industrial data acquisition
Wireless data communication
Note: High quality 3.3V LDO is integrated, and Pin CS / SET are 3.3V interface. TXD/RXD is also 3.3V for LoRa610-TTL
The typical schematic circuit is as below:
Note: The ground pin of the module and device should be connected together
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, as below:
2) Working Mode
The CS and SET Pin is internally pulled up. Pull CS pin high or leave it open will make LoRa611 enter into working mode.
In working mode, LoRa611 stay in receiving mode and wait for the series signal and RF signal.
Lora611 can connect with any device which is standard TTL interface.
When series signal comes, LoRa611 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, LoRa611 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 easiest way to test the module is using computer( PC software)
