Product overview
The MAD AM32 100A 3-12S 4in1 ESC combines four electronic speed controller channels in a compact UAV propulsion component. Each channel carries a 100A continuous rating and a 120A maximum rating limited to five seconds. Its 55 × 59 × 8 mm dimensions, 40.5 mm screw hole spacing and 38.3 gram weight excluding wiring define the installation footprint. Each ESC integrates a three-in-one H-bridge driver, with NXP automotive grade MOS components and an STM32L431/432 Cortex-M4 processor.
The selected configuration uses AM32 firmware; the listed alternatives are ESCape32 and BLHeli_32, with BLHeli_32 identified as 31.83 TEST. Control inputs include PWM, Dshot150/300/600/1200, Oneshot 125/42 and Multishot. An 8P silver-plated locking socket provides the flight controller cable connection, while four independent current and voltage detection channels require telemetry and ESC sensor settings. BEC output is specified as none despite a separate onboard high-voltage BEC description. Its 100V tolerance applies only to that BEC, not the complete ESC.
