• Introduction and Operation Video of Mesh Node T114 Development Board
• Why do we need Maker series products?
• Low Power Chracteristics
• 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
• 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 deg C, 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.
