🔌 Installation & Wiring​

Power Connection​

  1. Mount the ESC using vibration-isolating rubber dampers.
  2. Solder battery leads directly to the VBAT (+) and GND (−) pads.
  3. Install the included low-ESR capacitor across VBAT and GND as close to the ESC as possible.

⚠️ Always verify polarity before applying power.

Flight Controller Connection​

  1. Connect the ESC signal harness to the flight controller ESC header or pads.
  2. Confirm proper alignment of:
    • VBAT
    • GND
    • Motor outputs (M1–M4)
    • Current sense
    • ESC telemetry

🧠 AM32 Firmware Overview​

The Ewing 80A ESC runs AM32, a modern open-source 32-bit ESC firmware offering:

  • High-speed motor response
  • Advanced telemetry and RPM feedback
  • Configurable PWM frequency and timing
  • Broad compatibility with modern flight controllers
  1. Open Betaflight Configurator
  2. Navigate to Configuration → ESC/Motor Features
  3. Set:
    • ESC Protocol: DSHOT600
    • Enable Bidirectional DSHOT (if supported)
  4. Save and reboot

Telemetry Setup​

  1. Go to the Ports tab
  2. Enable Telemetry on the UART connected to ESC telemetry
  3. Save and reboot

Motor Verification​

  1. Remove propellers
  2. Use the Motors tab to confirm:
    • Correct motor order
    • Correct motor direction
  3. Reverse motors in software if needed

🔧 AM32 Configurator (Advanced Tuning)​

Advanced tuning options include:

  • PWM frequency (24–48 kHz typical)
  • Motor timing
  • Startup power / boost
  • Braking strength
  • Telemetry output mode

⚠️ Make incremental changes and test at low throttle.

⚠️ Safety Notes​

  • Always remove propellers during setup
  • Use a smoke stopper for first power-on
  • Verify solder joints and insulation
