RadioMaster: MT12 Surface Radio Controller

The RadioMaster MT12 is a pioneering open-source surface radio, and the first surface radio officially supported by EdgeTX, ExpressLRS, and the Multi-module project. Boasting 10 physical inputs and the capability to handle either 16 or 32 channels*, the MT12 is primed for a wide array of surface models, from cars and trucks to boats and beyond. Featuring extensive customizability and a versatile operating system, the MT12 stands out as a highly configurable surface radio, prepared to excel in virtually any scenario.
