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. Mesh Node T114 has been upgraded to ReV2.0 version with the following changes made : · The circuit board was changed from 4 layers to 6 layers so that both the RF part and the crystal oscillator part can obtain a more complete ground. · The circuit was changed from lead-free to immersion gold process, which is more friendly to signal transmission. The position of some components was adjusted. · The RF path was optimized according to the six-layer board structure. · The direction of the 2.4GHz Bluetooth antenna and IPEX LoRa antenna interface was changed to make them farther away. · The data transmission can sent long data packets on meshtastic.
Integrated High-Sensitivity GNSS for Precision Tracking: Equipped with onboard GPS/BeiDou positioning module, this node delivers accurate location data for Meshtastic network telemetry. Perfect for outdoor adventures, asset tracking, and emergency response where real-time position sharing across the mesh is essential—no cellular coverage required.
Ultra-Low Power Consumption for Extended Field Deployment: Powered by the nRF52840 MCU and SX1262 LoRa chip, this V2 node consumes as little as ~11µA in deep sleep. Combined with support for LiPo batteries and solar panel input, it offers weeks or even months of operation for remote, off-grid mesh networking applications.
V2.0 Hardware Upgrade for Enhanced RF Stability: The Rev 2.0 board features a 6-layer PCB with immersion gold process, significantly improving signal integrity and RF isolation. This design minimizes interference between Bluetooth and LoRa interfaces, ensuring more stable long-distance communication compared to previous versions.
Vivid Onboard Display for At-a-Glance Monitoring: The 1.14-inch TFT-LCD display (135x240, 262K colors) shows critical mesh information including node status, telemetry data, GPS coordinates, and message activity directly on the device—reducing dependency on a smartphone for field operations.
Versatile Development Platform with Full Connectivity: Beyond Meshtastic firmware, this board serves as a powerful nRF52840 development platform featuring USB-C with ESD protection, dedicated JST connectors for LiPo battery and solar panel, and external antenna interface. Ideal for LoRaWAN, Arduino, and Zephyr-based IoT projects requiring location awareness.
