MicoAir AM32 70A 4-in-1 ESC
Description:
The MicoAir AM32 70A 4-in-1 ESC is a high-current electronic speed controller designed for FPV drones and multirotor UAV applications. It integrates four motor controllers into a single compact board, supporting up to 70A continuous current per channel. Powered by AM32 firmware and a 32-bit processor, it supports PWM, DShot300, and DShot600 protocols for responsive brushless motor control. Compatible with 3–6S LiPo batteries, this ESC is suitable for larger FPV freestyle, long-range, and multirotor drone builds. Its metal-packaged MOSFETs help improve heat dissipation during operation.
ESC Specifications
- ESC firmware: AM32_F4A_4IN1_F421_2.19
