Description 2-4S 32-Bit ESC AM32 Improved Version High-Performance Speed ​​Controller A The ultra-compact 32-bit controller is ideal for compact installation and is a drive tool for various brushless motors in small model aircraft. The low-power side-mounted MOSFET ensures optimal heat dissipation and high performance. Minimal form factor and high performance – ideal for small aircraft, tracked vehicles, and climbing vehicles. The improved version integrates the BEC module (5V/2A) based on the same standard size, supplemented with overcurrent copper rails and thermally conductive silicone sheets, thus increasing performance. Supports common control signals such as DSHOT and PWM with linear behavior at low speeds, aggressive behavior at high speeds, and smooth speed control. The AM32 open-source firmware is freely customizable. It supports bidirectional operation, adjustable brake, sine wave start, and other functions. Fast forward and reverse switching is extremely smooth. Attention! It is strongly recommended to install a high-capacity electrolytic capacitor (NOT included, you will need to provide one yourself) outside the controller to improve its performance!
