Complete replacement and expansion kit for PX4 and PIX 2.4.8 compatible autopilot systems. This package gives you a ready set of parts to install, upgrade, or 32bit flight controller setups for RC aircraft and drones. Key benefits Direct compatibility: Designed to work with Pixhawk and PX4 autopilot setups and the PIX 2.4.8 32bit flight controller form factor, so it fits existing mounts and wiring standards. Ready to install: Includes the core flight controller plus essential peripherals for immediate use, reducing the need to source individual parts. Improved performance: 32bit processing provides smoother control loops and better sensor handling compared to older 8bit controllers. Expandable sensor support: The included I2C splitter module lets you add multiple I2C devices such as GPS, magnetometer, and additional sensors without rewiring the core bus. Reliable logging and configuration: 4G SD card supports onboard data logging. USB interface simplifies firmware setup and parameter tuning. Practical safety and convenience: External switch and buzzer provide easy power control and audible status alerts during bench testing and preflight checks. Modular and serviceable: Replacement parts and USB cable included in Style A kit simplify maintenance and field repairs.
