"Documented" means the maker or project publishes support for this model. It does not mean we tested it. How we rate compatibility.

MeshCore and Meshtastic are separate firmware and network systems. Check the exact hardware model, firmware, regional radio setting and local coverage before buying. These low-data-rate systems do not replace emergency services or broadband.

Operate radio equipment within your local frequency, power and equipment-authorization rules. Firmware compatibility is not regulatory approval.
