Description
The Matek G474-HELI is a high-performance flybarless flight controller designed specifically for RC helicopters. Equipped with the powerful STM32G474CE MCU running at 170MHz and 512KB Flash memory, this controller ensures smooth and responsive control for both 2S and 6S LiPo battery setups. Its advanced sensors, including the ICM42688-P IMU and SPL06 barometer, provide exceptional stability and precision during flight.
This flight controller features 3 UART ports, 1 I2C interface, and 8 PWM outputs suitable for 4 servos, 2 motors, RPM signals, and LED control. The integrated 128MB Flash (1G-bit NAND) blackbox allows for extensive flight data logging. With an input voltage range of 5.4V to 30V (2S to 6S LiPo), the G474-HELI supports a wide array of power configurations. The onboard BEC provides 5V at 2A for the flight controller and peripherals, while a separate BEC delivers up to 5A continuous (8A peak) for servos, with selectable voltage options of 5V or 7.2V.
The G474-HELI comes preloaded with Rotorflight firmware, offering pilots unmatched precision and responsiveness. Its compact design, measuring 38 x 26 x 13 mm and weighing just 15g without pins, makes it an ideal choice for various RC helicopter models. The package includes a PicoBlade 1.25mm servo adapter, JST-GH cables, and unsoldered Dupont 2.54 pins for customizable setup.
