Heltec Mesh Node T114 Rev 2.0 (nRF52840 + SX1262, Display) Meshtastic & MeshCore EU868

A versatile low-power mesh node with a built-in display, ready for Meshtastic or MeshCore. The Heltec Mesh Node T114 Rev 2.0 combines an nRF52840 processor with an SX1262 LoRa radio and a 1.14" colour TFT display, all in an ultra-low-power design. This version is configured for the EU868 band with the display, making it an excellent choice for a fixed node, a repeater, or a desktop mesh device where you want to see status and messages at a glance.

It works straight out of the box with every other Meshtastic and MeshCore device on your local mesh.

This Version's Configuration

• Band: EU868 (863–870 MHz)
• Display: included (1.14" colour TFT)
• GPS: not included in this version. Ideal for fixed nodes and repeaters where position is static. If you need GPS for tracking, see our GPS-equipped nodes such as the Mesh Node T096

Why the T114?

• Colour TFT display: a 1.14" screen (135 x 240, up to 262k colours) shows messages, node status, and signal information directly on the device
• Ultra-low power: the nRF52840 draws just 23 µA in Meshtastic low-power mode, far below ESP32 boards, for excellent battery life on fixed nodes
• Reliable LoRa: the SX1262 radio provides solid long-range performance
• Flexible power options: USB-C, lithium battery, and solar panel connectors, so you can run it however your deployment needs
• Bluetooth 5.0: pair with the Meshtastic app on your phone for full messaging

What You Can Build

• Fixed mesh node: a reliable always-on node for your home, office, or a fixed location, with a display to monitor activity
• Mesh repeater: extend the range of your local network from a static position
• Desktop Meshtastic device: a compact node with a clear colour display
• Solar-powered node: connect a solar panel and lithium battery for autonomous operation
