LightTracker Plus is an ESP32-based development board featuring a 1 Watt SX1268 (433MHz) LoRa module, GPS module, battery holder, and 2 dBi 433 MHz SMA antenna.

Information, source code

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

Key Features

• Ready-assembled PCB: all components are SMD and already soldered
• Open Source: Shipped with preloaded basic LoRa APRS Software (Tracker, iGate or Digipeater) The source code is shared via GitHub
• GPS Balloon Mode: for high altitude up to 80km (Convenient for High Altitude Balloon tracking)
• Arduino Compatible MCU: Since ESP32 is Arduino compatible, you can use VSCode or Arduino IDE and libraries to program LightTracker Plus 1.0.
• Extendable: Using I2C and SPI pins you can add extra sensors (and their libraries) to LightTracker Plus 1.0 and program it as you wish.
• 1 Watt Radio: Powerful 1 Watt LoRa radio module
• GPS Module with Active Antenna: Quectel L80-R, Compact GPS Module Integrated with Patch Antenna
