RadioMaster AX12 Android Radio Controller (ELRS)

RadioMaster AX12 Android Radio Controller ELRS LBT

The RadioMaster AX12 combines a powerful ExpressLRS radio system with the flexibility of an Android-based touchscreen platform. Designed for FPV pilots, drone builders, filmmakers, rovers, boats and advanced RC projects, the AX12 gives you precise control, app support and video integration in one compact transmitter.

At the heart of the AX12 is RadioMasterOS based on Android 9.0, with Google Play support and APK sideloading for compatible apps such as ground-station tools, configuration software and telemetry utilities. The bright 5.5-inch HD IPS touchscreen with 1280 × 720 resolution and 1000 nits brightness keeps menus, telemetry and video clearly visible outdoors.

Built-in ExpressLRS delivers up to 16 channels with 2.4 GHz or Sub-G 900 MHz operation, low-latency control and Wi-Fi OTA firmware updates. The high-precision X5 Hall-effect gimbals provide smooth, contactless stick control, while advanced mixing, custom curves, model templates, voice prompts and Lua script support make the AX12 suitable for complex setups.

With HDMI input and output, the AX12 can display compatible digital video feeds directly on its screen or mirror the display to an external monitor for teaching, reviewing or team use. Powered by dual built-in 21700 lithium batteries, with USB-C PD charging, Wi-Fi, Bluetooth and 64 GB internal storage, the AX12 is a modern control platform built for pilots who want more than a classic radio.
