Features: A new 32bit ESC Speed Regulator with mini size, perfect for compactly installation, and is a driving tool for various small aircraft brushless motors. Choose low-power transistors and place the layout on the same side for heat dissipation and powerful power. Mini size and highly power is the preferred power sources for small aircraft, crawlers, and climbing vehicles. The upgraded version integrates the BEC module (5V2A), adds overcurrent bar, and adds thermals conductives silicone sheets on the basis of the unchanged size of the standard version, elevating all performances to a higher level. Support mainstream control signal such as DSHOT and PWM, low-speed linears, highly-speed violent, and smooth speeds control. Using AM32 open-sources firmware, it can be freely adjusted. Supports bidirectional operation, adjustable drag brake, sines start, and other functions, with smooth switching between forward and reverse directions. It is strongly recommended to install large capacity capacitors outside of ESC (not included) to improve its working conditions!
