ESC main control: master control+drive 2-in-1 integrated chip, QF32F4A = AT32F421 + ID6288 MOS istor model: HYG022N04LS1C1, On-Resistance of 2.0mΩ (compared to other similar products that use MOS internal resistance of around 3mΩ), withstand voltage of 40V, 6S Lipo stable operation. Onboard 12pcs 0805 capacitors, each with a capacity of 2.2uF, totaling 26.4uF, far exceeding other similar products, providing stable power filtering. Used for RC model airplane, car model. 32-bit main control, support sine wave startup (default off), factory flashed AM32 firmware, fixed wing aircraft and racing drone can be used directly. ESC can also flash BL32 firmware or HF32. No onboard BEC, can be used for mosquito cars, RC car models require external BEC for use. All ESCs are tested for rotation before leaving the factory. Item name: mini ESC Working voltage: 2-6S (6V-26V) ESC size: 22.7x13.8x3.8mm/0.89x0.51x0.15in ESC weight: about 2.2g (0.005 pounds) Nominal current: 40A continuous/50A instantaneous (due to its small size and limited heat dissipation capacity, the ESC has limited ability to sustain overcurrent, and can maintain stable 20A continuous in windless environments) PCB process: black, resin plug hole, hole in pad, copper thickness 2OZ. Attention: The image is a test version PCB, subject to actual receipt. Due to severe heating caused by the ESC, there is no heat shrink film inside the packaging, and it is not recommended to use heat shrink film. At the same time, it is important to note that during the installation of the ESC, it should not be connected to other conductors (carbon fiber board, battery plug, other circuit boards) to avoid external short circuits and damage.
