RadioMaster TX15 Radio Controller (ELRS / M2) RadioMaster continues to redefine the open-source remote control landscape. After years of collaboration with our open-source partners and users, we are proud to introduce the RadioMaster TX15 Radio Controller Driven by the high-performance STM32 H7 chip, it’s the powerhouse behind our fastest radio ever — enabling ultra-smooth EdgeTX control, instant model switching, and lightning-quick script execution. With 4GB of flash storage and MicroSD card expansion, you’ll have virtually unlimited space for models, scripts, sounds, and themes. The TX15 features an LR1121 Semtech transceiver, supporting both 2.4GHz and 900MHz ExpressLRS (ELRS) for exceptional low-latency performance. Whether you’re using it daily or in challenging RF environments, the TX15 is engineered to deliver reliable results. A smart balance battery circuit optimizes runtime, while the compact, foldable antenna design enhances portability and maintains strong signal quality. The built-in gyro with TiltX/TiltY functions unlocks advanced control options, allowing you to trigger switches, adjust accessories, or activate telemetry features with a simple tilt of your radio. This versatile module combines durability, ease of use, and innovative features, making it an outstanding choice for demanding setups. Experience clear visuals on the 3.5-inch IPS touchscreen with 262k color resolution and 600 nits brightness, visible in sunlight. The TX15 Standard features V5.0 hall sensor gimbals in six vibrant colors. It’s advanced cooling, a USB-C port for charging, SIM connectivity, firmware updates, and high-speed memory access ensure reliable performance. We’ve included additional switches so you can swap out the shoulder buttons with either a momentary or two-position latching switch—perfect if you prefer a traditional switch over a button.
