Heltec L76K GNSS Module for WiFi LoRa 32 V4 and T114
Give your Meshtastic node the ability to know its position! The Heltec L76K is a compact GNSS module with a built-in antenna, which connects to a compatible board using the included 8-pin cable.
The module is compatible with the Heltec WiFi LoRa 32 V4 and Mesh Node T114 and is suitable for location sharing and projects where you want to track a node's location. It can be used with an 868 MHz LoRa node, but the GNSS module receives satellite signals and does not have an 868 MHz LoRa radio itself.
The GNSS module is sold separately from the development board. Position the antenna with a clear view of the sky for the best reception.
The L76K supports multiple satellite systems: GPS, GLONASS, BeiDou, and QZSS. The module sends position data to the board via UART, typically at 9,600 baud. NMEA messages can contain coordinates, UTC time, satellite status, and speed. The built-in low-noise amplifier and SAW filter help receive and filter the signals. The stated CEP accuracy is a statistical value under test conditions, not a guarantee in all environments.
