- Advanced LoRa Mesh Networking Solution with GT-800 Soft Antenna: The Heltec T114 development board features nRF52840 + SX1262 chips for powerful LoRa (902-928MHz) and Bluetooth 5.0 connectivity. Equipped with the GT-800 high-gain soft antenna, this Meshtastic-compatible node offers 21dBm transmit power and -135dBm sensitivity, enhancing signal stability and range for long-distance IoT projects. The upgraded 6-layer PCB with immersion gold process ensures stable RF performance in Meshtastic networks and LoRaWAN deployments.
- Ultra-Low Power with 3000mAh Battery & Solar Ready: Engineered for efficiency, this T114 board consumes only 11µA in LoRaWAN deep sleep and 23µA in Meshtastic mode. The integrated 3000mAh lithium battery and solar panel connectors (1.25×2P) enable extended off-grid operation. The GT-800 antenna’s low-power design complements the board’s energy-saving features, making it ideal for remote sensors and environmental monitoring (-20°C to 70°C range).
- 1.14" TFT Display & Expandable Interfaces:Features a vibrant 1.14-inch TFT-LCD (262K colors) for real-time data visualization. Offers multiple connectivity options including Type-C USB, LiPo connectors, IPEX antenna port (compatible with GT-800 or external antennas), and 2×13-pin headers (UART/SPI/PWM). Fully compatible with Arduino IDE for custom development.
- Optimized for Meshtastic & Open-Source Projects: Pre-configured for Meshtastic firmware with stable Long_Fast channel performance. The GT-800 antenna’s flexible installation adapts to protective shells, enhancing durability and heat dissipation. Perfect for DIY mesh networks, asset tracking, and smart agriculture with open-source compatibility.
- Professional IoT Development Platform: This complete LoRa solution combines nRF52840 MCU, SX1262 LoRa chip, GT-800 soft antenna for robust RF performance, and comprehensive power options (USB/battery/solar). With Bluetooth mesh support and low-power design, it’s ideal for wireless sensors and IoT systems, from hobbyist prototypes to professional deployments.
