Low Power Chracteristics

 

Summary

The Mesh Node T114 features a dual-chip combination of nRF52840 and SX1262, simultaneously

 

supporting both LoRa and Bluetooth communication, with optional GPS and display modules; it achieves

 

flexible power management via USB, lithium battery, and solar panel interfaces, and exhibits superior

 

low-power characteristics compared to the Heltec V3; its six-layer PCB architecture and optimized RF

 

circuit design make it especially suitable and durable for LoRa/LoRaWAN applications such as device

 

tracking and remote monitoring systems; and finally, the T114 enables development through environment

 

like Arduino and PlatformIO, offering full compatibility with well-known open-source projects like

 

Meshtastic and MeshCore

 

 

 

 

 

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.

  • Powerful display function, onboard 1.9-inch TFT-LCD display contains 170 (RGB)X320 dots and can display up to 262k colors.

  • 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.
