The Compact, Rugged LoRa Node for Reliable Off-Grid Communication

Built for those who travel light but think big, the SpecFive Trekker Delta is a high-performance Meshtastic LoRa node designed for explorers, emergency responders, and mesh network builders. It’s compact, efficient, and built tough, ready to keep you connected when cell coverage fades.

Inside, the nRF52840 MCU delivers low-power performance with the SX1262 LoRa module for dependable long-range communication. The integrated GNSS module keeps your team’s positions in sync, while the replaceable 18650 Li-ion cell powers extended deployments with ease.

Delta ships fully assembled and field-ready. With dual antennas for LoRa and GPS, it locks in connectivity and location accuracy wherever it’s deployed. Its PETG enclosure is lightweight yet durable, designed to survive the bumps, dust, and elements of the trail or the field. It ships with a choice of either Meshtastic or ATAK firmware.

Just power it up, no soldering, no setup and Delta joins the mesh, sharing your position and relaying messages over miles of terrain.
