A 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. The enhanced version integrates the BEC module (5V2A) on the basis of the standard versions unchanged size, adds overcurrent copper bars, adds thermal conductive silicone sheets, and takes all performance to a higher level. Supports mainstream control signals such as DS 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. Colour:As Shown Material:PCB Name: AM32 40A ESC Firmware: AM32 Master: AT32 Working voltage: 2-4S Output current: 30A continuous, 40A maximum Supported signals: PWM/DS /sine, etc. BEC module: Yes, 5V 2A Cable length: 10cm Size: 30x12x7mm Weight: 11g Attention! It is strongly recommended to install a large capacity electrolytic capacitor(NOT include, prepare by yourself) outside the ESC to improve its working condition!
