Yeti Wurks Solar Infrastructure Node (Next Generation)

A refined successor to our long trusted RAK based Meshtastic/Meshcore base stations, the new Yeti Wurks Optimized Base Station (OBS) brings two years of field experience into a custom engineered PCB designed for superior efficiency, power handling and long term reliability. It preserves the strengths of the original platform while elevating nearly every aspect of performance and usability.

*Testing is underway, with production release targeted for January. Prototype photos may vary slightly from the final version as final refinements are completed.

Purpose Built for Off Grid Performance

This next generation design remains compatible with existing firmware, supports current enclosure setups and is engineered to withstand harsh outdoor deployments. It features advanced power management, an industrial temperature rating and targeted quality of life improvements, all while maintaining the same price target as the current base station line.

Key Features
