A brushless motor controller, designed by AI

Motion control boards mix a dirty 12 V power domain with sensitive logic. This board takes a barrel-jack input, steps it down with a buck converter sized for the load, and drives a standard ESC from an ESP32 — the throttle signal, the rails, and the connectors all checked before you order.

What ends up on the board

  • 12 V barrel-jack input, fused and protected
  • Buck converter to a 3.3 V logic rail
  • ESP32 module for control and connectivity
  • Throttle output to a standard brushless ESC connector
  • Status LED and programming header

How Ohmni designs it

  1. The circuit is generated from your description: the buck sized for continuous and peak load, the ESC interface wired to a PWM-capable pin.
  2. Rails are simulated and the layout is verified against manufacturing rules before you see it.
  3. You download gerbers, a BOM, and a 3D preview, ready for your fab.
