Radio Controller RadioMaster TX15 Radio Controller (ELRS / M2)

The RadioMaster TX15 is an open-source radio controller built on the high-performance STM32 H7 processing architecture, delivering exceptionally fast execution speeds. This advanced processing overhead guarantees seamless EdgeTX operating system performance, near-instantaneous model profile switching, and rapid Lua script execution.

Features

Next-Gen Processing Power: Driven by an ultra-fast STM32 H7 processor minimizing system latency and unlocking fluid multi-tasking and quick script calculations.

High-Visibility Touchscreen: Features a 3.5-inch IPS color touch display with a 480x320 resolution, 262k colors, and 600 nits of brightness for clear viewing under direct sunlight.

Dual-Band RF Architecture: Integrated Semtech LR1121 transceiver supporting ExpressLRS (ELRS) operations across both 2.4GHz and 900MHz frequencies for unmatched long-range link redundancy.

Elite Gimbal Precision: Equipped with high-precision V5.0 Hall-effect sensor gimbals offering frictionless stick feel, adjustable tension, and permanent wear resistance.

Massive Storage Capacity: Configured with 4GB of high-speed onboard flash memory alongside a dedicated MicroSD card slot for virtually limitless storage of models, telemetry data, and custom audio scripts.

Advanced Thermal Control: High-efficiency cooling system utilizing an internal aluminum heatsink and silent active cooling fans to combat thermal buildup during high-power output sessions.

Integrated TiltX/TiltY Gyroscope: Onboard motion tracking allows pilots to assign controller tilts to manage custom camera axis configurations, auxiliary switches, or telemetry screens.

Modular Mechanical Layout: Features interchangeable toggle switch assemblies that allow you to hot-swap between latching two-position and momentary short switches based on ergonomic preference.

Smart Power Management: Advanced internal battery balance charging circuitry designed to maximize cell efficiency and extend single-charge field runtime.
