Mesh Node T114 is a development board based on nRF52840 and SX1262, supports LoRa and Bluetooth 5.0. It integrated a variety of power interfaces (5V USB, lithium battery and solar panel), optional 1.14 inch TFT display and GPS module as ,can display up to 262k colors. and has powerful long-distance communication capabilities, scalability, and low power design,11 uA in deep sleep. 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.with Arduino,-USB interface with a complete voltage regulator, ESD protection, short circuit protection, RF shielding, and other protection measures.
nRF52840 + SX1262 Dual-Core Long-Range Platform:Built with nRF52840 (64MHz Cortex-M4F, 256KB SRAM, 1MB Flash) and Semtech SX1262 LoRa chip. Delivers 21±1dBm TX power and -135dBm sensitivity. Supports LoRa, Bluetooth 5.0 BLE & Mesh. Pre-flashed with Meshtastic firmware—ready for off-grid communication out of the .
Ultra-Low Power for Days of Field Use:Deep sleep current as low as 11µA. Pair with a large Li-ion battery and GNSS tracking runs for days. Optimized sleep modes for Meshtastic applications—perfect for battery-powered outdoor IoT nodes, remote sensors, and GPS trackers.
Triple Power Input for Off-Grid Deployment:USB-with full ESD/short-circuit/RF protection. SH1.25-2P ports for both Li-ion battery and solar panel input. Supports 3.7V Li-ion and solar charging—ideal for remote, unattended installations in the field.
Open-Source Ready with Rich I/O:Fully with Arduino and nRF52 framework. Offers SPI, I²C, UART, PWM interfaces. Optional 1.14" TFT-LCD (135×240, 262K colors) and L76K multi-constellation GNSS module (GPS/GLONASS/Galileo/BDS/QZSS). Wide -20℃ to 70℃ operating range.
Plug & Play with Meshtastic:UF2 drag-and-drop firmware flashing (DFU mode: double-tap reset). Works with Meshtastic, MeshCore, and LoRaWAN out of the . Revised V2 circuit with enhanced RF shielding ensures stable performance for remote monitoring, outdoor mesh, and asset tracking projects.
