What it does

  • Designed for smooth, fast startups and linear throttle response across multiple vehicle types.
  • Can be built with crawler support.
  • Firmware can be upgraded via Betaflight passthrough, single-wire serial, or Arduino.
  • Supports servo PWM and Dshot (300, 600) motor protocols, including bi-directional Dshot.
  • Provides KISS-standard ESC telemetry and variable PWM frequency.
  • Includes a sinusoidal startup mode intended to get larger motors up to speed.
