The 4in1-ESC-YTO is a new-generation three-phase brushless motor drive solution built around a 32-bit high-speed MCU. Its 4-in-1 integrated design combines four independent 60A continuous channels (80A burst) on a single board, simplifying frame assembly while delivering high efficiency and fast, responsive throttle handling. The drive stage supports high-frequency PWM, DSHOT and ONESHOT protocols, with hardware synchronous rectification, regenerative braking and stall protection for cleaner deceleration and improved energy recovery. Wide 6V–28V input covers 2S–6S Li-ion batteries. Compact (43.5 × 44.0 × 8.3 mm) and lightweight at roughly 20.0 g, it is suitable for small aerial-photography drones and small-to-medium FPV builds.

Thank you for choosing a CORVON product. Please read this disclaimer carefully — by using this product, you acknowledge and agree to the following: brushless power systems can be dangerous, and improper use may result in personal injury or equipment damage. Follow the installation and operation instructions carefully. Because we cannot control how this product is used, installed, or maintained, we accept no liability for any loss or damage arising from its use. Any unauthorized modifications are at your own risk.
Read this manual to understand all power configuration parameters before powering the system. Installation requires soldering and wiring. Make sure all wires are properly insulated before connection to avoid short circuits, and use a soldering iron with adequate power to ensure solid joints — poor connections can overload the motor and damage the unit. After use, always disconnect and remove the batteries. This open-source ESC can only be flashed with the specific firmware; using the wrong firmware can stop the ESC working or damage the internal chip. This ESC is intended for multi-rotors with a diagonal wheelbase under 300 mm; using it beyond this limit may damage the ESC or cause other issues, for which the user is responsible.
