Control Protocol (PWM)

  • Signal: 3.5V-5V PWM, 50Hz

  • Neutral: 1.5ms (motor stops)

  • Forward: 1.0ms→1.5ms (closer to 1ms = faster)

  • Reverse: 1.5ms→2.0ms (closer to 2ms = faster)

  • Critical: Must share ground with control board

Applications

  • Underwater robots (ROVs)

  • Surface vessels & boats

  • Subsea equipment & sensors

  • Research and exploration devices

Important Notes

  • 🔸 Requires technical expertise for operation

  • 🔸 Power + PWM signal must be supplied simultaneously

  • 🔸 Thrust reduces with guard installed

  • 🔸 Exceeding 25.2V may damage built-in ESC

Simple ESC Matching Guide

Voltage (V):

ESC voltage = Battery voltage (e.g., 3S LiPo = 12V, 6S LiPo = 24V).

Current (A):

ESC current ≥ Motor max current + 20-30% safety margin.

Quick Examples:12V, 20A motor → 30A ESC (or higher).

Rule: ESC can handle higher amps than needed, but never lower. Always check motor specs!
