Yes. While the internal module is a 4-in-1 MPM, the MT12 features a standard Nano module compartment. You can install an ExpressLRS Nano transmitter module (e.g., RadioMaster RP1 or similar) to add high-performance, low-latency ELRS control for compatible receivers. The radio's EdgeTX firmware fully supports external module configuration.

The MT12 uses a single 18650 Li-ion cell (or equivalent 2S LiPo) via the included battery tray. It features a built-in USB-C port with Qualcomm Quick Charge 3.0 (QC3.0) support, allowing for fast charging at up to 2.0A. The operational voltage range is 6.6V to 8.4V.

The MT12 supports 16 or 32 channels via its EdgeTX firmware. It comes equipped with 10 physical inputs, including pots, switches, and two gimbals. The package also includes expansion modules to add either two additional switches or a 4-way joystick, allowing you to customize the control layout for complex surface models like crawlers or boats.
