Mesh Node T114 is a Low Power Consumption development board based on nRF52840 and SX1262, supports LoRa and Bluetooth 5.0 . which integrated various 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.

Mesh Node T114 has been upgraded to ReV2.0 version with the following changes made :

•  The circuit board was changed from 4 layers to 6 layers so that both the RF part and the crystal oscillator part can obtain a more complete ground.
• The circuit was changed from lead-free to immersion gold process, which is more friendly to signal transmission.
• The position of some components was adjusted.
•  The RF path was optimized according to the six-layer board structure.
• The direction of the 2.4GHz Bluetooth antenna and IPEX LoRa antenna interface was changed to make them farther away.
• Now the high-frequency Mesh node T114 can stably send long data packets in the “Long_Fast” channel of Meshtastic.
