LightGateway is an ESP32-based development board featuring a SX1268 (433MHz) LoRa module and a 2dBi 433 MHz SMA antenna.

Information, source code

Official information and source code is on GITHUB: https://github.com/lightaprs/LightGateway-1.0 

Key Features

• Ready-assembled PCB: all components are SMD and already soldered
• Open Source: Shipped with preloaded basic LoRa APRS Software (iGate or Digipeater) The source code is shared via GitHub
• Arduino Compatible MCU: Since ESP32 is Arduino compatible, you can use VSCode or Arduino IDE and libraries to program LightGateway 1.0.
• Extendable: Using I2C and SPI pins you can add extra sensors (and their libraries) to LightGateway 1.0 and program it as you wish.
• SMA Antenna: 2dBi 433 MHz (included)
