HELTEC T114 V2 MESH T-TRACKER DEVBOARD

Nordic nRF52840 + SX1262 LoRaWAN Node with TFT Display & Battery

The Heltec T114 V2 Mesh Node is a powerful development board designed for LoRa/LoRaWAN and Meshtastic applications. Combining the low-power Nordic nRF52840 MCU and the long-range Semtech SX1262 LoRa chip, this device offers superior communication and scalability for your IoT, tracking, and amateur radio projects.

Key Wireless & Processing Features:

• MCU & LoRa Chip: Features the nRF52840 MCU for processing and SX1262 as the LoRa Node Chip for reliable, long-distance communication.
• Connectivity: Supports Bluetooth 5 (including Bluetooth mesh) and LoRa, with optional WiFi integration.
• Frequency: Operates on standard LoRa frequencies (868MHz / 915MHz - check regional variants for full range).
• Low Power: Excellent efficiency with a minimal consumption of 11 uA in deep sleep, ideal for battery-powered, remote deployments.
• High Sensitivity: Max. Receiving sensitivity of $-135\text{ dBm} @ \text{SF12 BW}=125\text{KHz}$ ensures long-range signal pick-up.

Onboard Hardware & Display:

The T114 V2 offers extensive hardware resources for development, all housed in a compact form factor (50.80 * 22.86\text{mm}$).

• Display: Includes an onboard 1.14 inch TFT-LCD display (optional) for real-time data and status updates.
• Power Flexibility: Equipped with Type-C USB, a LiPo battery connector (for the included 3.7V/800mAh battery), and a solar panel connector for truly independent operation.
• Interfaces: Plenty of resources for expansion, including USB 2.0, SPI, TWI, UART, PWM, and a dedicated GPS module connector.
• Development: Compatible with the Arduino framework, simplifying coding and project creation.
