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.
