Heltec Automation Mesh Node T114 Rev.2 LoRa 863-870MHz mit Display und GPS

The Heltec Mesh Node T114 Rev.2 is a powerful development board that supports both LoRa and Bluetooth 5.0. Thanks to the efficient nRF52840 microcontroller and the SX1262 LoRa chip, this board is ideal for wireless networks, IoT projects, and Meshtastic applications. It features versatile power supply options, including 5V USB, lithium battery, and solar panel connection. A 1.14-inch TFT display allows for comfortable data visualization, while an integrated GPS module connector ensures positioning and tracking capabilities. The revised Rev.2 version brings improved signal stability, optimized RF performance, and a high-quality gold-plated PCB that ensures better durability and signal transmission. With Heltec's compatible development environment, the board can be easily configured for LoRaWAN or Meshtastic networks.
