MORE AFFORDABLE. STILL GRUMPY.
The Grumpy Jr Repeater
The Grumpy Jr Repeater is our streamlined, more affordable solar-powered MeshCore repeater.
It uses a much smaller Grumpy Mesh enclosure, with a stripped-down internal design and fewer
features than the Grumpy King Repeaters — giving you the core repeater capability at a more attractive price.
It features a Heltec V4 Radio for 27dbm transmitting and wifi firmware updating.
Inside the Grumpy Jr
We've taken the Grumpy Mesh design and simplified it without losing the features that matter most. The Grumpy Jr is built around a compact, efficient setup designed for outdoor and off-grid MeshCore deployments.

- Weatherproof USB connector — for programming and service
- N-Female bulkhead connector to IPEX — a clean antenna connection from the radio to the external antenna

- Choice of rear enclosure — select the back configuration that works for your installation
