LoRa Transceiver

Overview

Our project focuses on developing a device that enables people to communicate via LoRa. The inspiration for the project was to facilitate messaging in areas with limited or no access to conventional wireless communication networks. The idea is that due to the low power consumption of LoRa and its extensive range, emergency communication could still be ensured in challenging environments.

Features

• ESP 32 Slot 

• LoRa Modem:

  • Uses license-free ISM band frequency

  • ~100mA peak during +20dBm transmit, ~30mA during active radio listening.

  • +5 to +20 dBm up to 100 mW Power Output Capability

  • Range of approx. 2Km, depending on obstructions, frequency, antenna and power output

• USB-C Connection for I2C

• Micro SD card slot

Schematic

Our routing could have been a bit better, but it gets the job done.

Future Directions

• Assemble pair of LoRa transceivers

• Write drivers to use as external network adapters 

• Test in rural regions where device might be useful along with replication strategies to integrate it to such communities
