Overview

MAD AM32 70A 3-8S ESC is an AM32 (open-source) brushless motor ESC designed for multi-rotor builds requiring high-current drive and digital throttle protocols. The board marking also shows “2-8S ESC / 2-8S LiPo”, and both voltage ranges are listed in the specifications below for accuracy.

Key Features

  • AM32 firmware (open-source)
  • Bidirectional DShot (RPM telemetry)
  • Active Freewheeling (reduces heat)
  • Customizable PWM frequency up to 48 kHz
  • Infineon “Aviation Grade MOS” (as labeled)
  • Integrated 3-in-1 driver with real-time monitoring of working current and voltage (as described)
  • Online upgrade: directly download firmware from the network (as described)
  • Imported TDK low-ESR capacitor: 240 uF total capacity, 35 V (as labeled)
  • Processor: STM32G071 (64M working frequency, as labeled)
  • Current sensor: Support (as listed)
  • Telemetry feedback: Support (as listed)
