Built for the place where your signal stops
Install a self-powered relay at a high, sun-exposed point to bridge difficult terrain, reduce dead zones and add a dependable hop to your mesh—without running mains power or scheduling routine charging trips.
High-power LoRa link
Up to 22dBm radio output helps create a stronger, more dependable long-range mesh link in open and challenging environments.
Energy-autonomous design
A 5W solar panel and integrated 5200mAh battery support continuous off-grid operation through normal day-and-night cycles.
Ready for outdoor deployment
The IP65 enclosure and tempered-glass solar surface are designed for exposed installations where rain, dust and changing weather are expected.
Two mesh ecosystems
Use the hardware with Meshtastic or flash MeshCore Repeater firmware, giving you flexibility as your network design evolves.
A compact relay with the essentials built in
LoRa radio, GNSS, solar harvesting, battery storage and status indicators are integrated into one mountable outdoor unit. The supplied antenna covers the 868–926MHz range.

⚠ Hardware upgrade warning — check polarity first
Before replacing or upgrading the internal Mesh Node EVB (for example, to a 30s Relay / 30s Solar Relay), disconnect the solar panel and battery, then verify the positive (+) and negative (−) pins before plugging in the connector.
The power polarity of the 30s Solar Relay is reversed relative to the GAT562’s original internal Mesh Node connection. Do not assume the connector orientation or wire positions are the same. Connecting it with reversed polarity can immediately and permanently burn out the main board.
Confirm +/− using the board markings and a multimeter, and repin or adapt the connector if required before applying power.
MeshCore repeater firmware
Flash the dedicated GAT562 repeater build directly from the official MeshCore web flasher. A compatible browser and USB connection are required for flashing.
Where it fits
One well-positioned relay can transform a fragmented network into a more useful, resilient communications layer.
Ridges & trail networks
Add a high-elevation hop between hikers, camps or valleys where direct node-to-node paths are unreliable.
Farms & remote property
Extend mesh coverage across fields, outbuildings and locations beyond dependable cellular service.
Community mesh coverage
Place a relay on a suitable rooftop or mast to strengthen links between separated neighborhoods or local nodes.
Preparedness & field operations
Build a self-powered communications layer for planned events, field research and contingency use.
Deploy in three steps
Flash your platform
Choose Meshtastic or MeshCore and configure the region, channel and repeater role for your network.
Test before mounting
Confirm radio operation, node visibility and battery charging at ground level before the final installation.
Mount high with clear sun
Favor line of sight, stable mounting and unobstructed solar exposure for the best radio and energy performance.
