Summary
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.
Main Features
- MCU nRF52840 (Bluetooth), LoRa chipset SX1262.
- Powerful display function (optional), onboard 1.14 inch TFT-LCD display contains 135(H)RGB x240(V) dots and can display up to 262k colors.
- Low power consumption, 11 uA in deep sleep.
- Operation condition: -20 ~ 70℃, 90%RH(No condensing).
- Type-C USB interface with a complete voltage regulator, ESD protection, short circuit protection, RF shielding, and other protection measures.
- Compatible with Arduino, we provide development frameworks and libraries.
- Various Interfaces: 1.25*2P LiPo connector, 1.25*2P Solar panel connector, 1.25*8P GNSS module connector, which greatly increase the extensibility of the board.

FAQ
The 2.4GHz antenna is a multilayer ceramic antenna for BlueTooth communications, it can’t be replaced.
- Arduino
- PlatformIO
In addition to Meshtastic support, we have also developed a complete LoRaWAN protocol in the nRF52 Arduino framework.
You can find this type of socket by search “SH1.25 x 2”.
The maximum capacity of the shell for carrying batteries is 42 * 28mm, and the default 3.7V lithium battery size is 41 * 24mm
Just download the screenless version firmware and enter the 123456 password.
5V~6.5V, it is recommended to connect solar panels with a voltage of around 5V.
Not time ago, customer reports that some of the Mesh Node T114 works as a Meshtastic device and tries to send long strings (>50 chars) ONLY in Long-Fast mode (SF11, 250K BW), sometimes sending messages may fail.
