1PCS AM32 32-Bit ESC 2-4S 40A Speed Controller for RC Crawler A new 32-bit ESC product, with a super mini size, very suitable for compact installation, it is a driving tool for various small model airplane brushless motors. Selected low-power MOS tube with layout placed on the same side for convenient heat dissipation and strong power. Mini size and high power, it is the preferred power for small aircraft, crawler, climbing vehicles. Integrates the BEC module (5V2A), adds overcurrent copper bars, adds thermal conductive silicone sheets, and takes all performance to a higher level. Supports mainstream control signals such as DSHOT and PWM, with linear at low speeds, violent at high speeds, and smooth speed regulation. It uses AM32 open-source firmware, which can be freely adjusted. It supports bidirectional operation, adjustable drag braking, sine start, and other functions, and fast forward and reverse switching is very smooth. With a 470uF 35V capacitor to improve its working condition.
