HELTEC T114 REV 2.0 MESH NODE: ULTIMATE LORA/GPS DEVBROAD
The Heltec Mesh Node T114 V2.0 is the completely revised, low-power development board for Meshtastic, LoRaWAN, and BLE tracking applications. Built on the Nordic nRF52840 MCU and the SX1262 LoRa chip, this second-generation board features a 6-layer PCB with immersion gold process for superior signal integrity and reliability. Available in multiple configurations, including GNSS, Screen, and Soft Antenna options.
Rev 2.0 Upgrades and Core Features
- Enhanced Stability (Rev 2.0): Upgraded from 4 to 6 PCB layers with immersion gold process, providing a more complete RF ground and superior signal transmission quality.
- Ultra-Low Power: Achieves a minimal 11 µA in deep sleep consumption, maximizing field deployment and battery life.
- Positioning Ready: Supports GNSS and GPS module integration (available as an option) via a dedicated 1.25x8P connector for precise location tracking.
- Dual Wireless: Features LoRa (SX1262) for long-range mesh networking and Bluetooth LE 5 (nRF52840) for local connectivity.
- Flexible Power Inputs: Integrates charging circuits for LiPo battery, Type-C USB, and Solar Panel via dedicated 1.25x2P connectors.
