Summary
Mesh Node T114 is a development board based on nRF52840 and SX1262, supports LoRa and
Bluetooth 5.0. It integrated a variety of power interfaces (5V USB, lithium battery and solar panel),
optional 1.14 inch TFT display and GPS module as accessories, and has powerful long-distance
communication capabilities, scalability, and low power design. With Heltec nRF52 development
environment and libraries , you can use it for LoRa/LoRaWAN development work, and also use it to run
some open source projects, such as Meshtastic.
