HELTEC Mesh Node T114 V2.0

nRF52840 LoRaWAN & Meshtastic Development Board

The Heltec Mesh Node T114 Rev 2.0 is an ultra-low power, highly integrated development board perfect for long-distance IoT and mesh networking projects. Combining the powerful nRF52840 MCU (Bluetooth 5.0) and the SX1262 LoRa Node Chip, the T114 V2.0 provides exceptional range, scalability, and efficiency for applications like Meshtastic, LoRaWAN deployment, and GPS tracking.

🛠️ V2.0 Engineering & RF Optimization:

The Rev 2.0 upgrade focuses on professional-grade signal integrity:

  • Enhanced RF Performance: Upgraded to a 6-layer circuit board structure for a more complete ground plane for the RF and crystal oscillator sections.
  • Superior Signal Transmission: Circuit board transitioned to the Immersion Gold process, optimizing signal transmission quality.
  • Isolation: Optimized component placement and antenna direction (2.4GHz and LoRa) to reduce interference.
