Custom ESP32-WROOM-32 robotics controller PCB with onboard buck/LDO power regulation, auto-program circuit, and BTS7960/RMCS/relay/servo interfaces. Designed in KiCad.

ESP32 Dual BTS7960 Motor Driver Breakout Board

A custom 2-layer PCB designed to handle heavy-duty robotics applications. It acts as a central control board breaking out an ESP32 to interface with dual BTS7960 motor drivers, an RMCS driver, and features onboard power regulation.

Features

  • Microcontroller: ESP32-WROOM-32
  • Power Stage: LM2596 Buck Regulator (12v to 5v switching) & AMS1117-3.3 (5v to 3.3v switching)
  • Motor Control Interfaces: 2x BTS7960 H-Bridge Drivers, 1x RMCS Driver interface
  • Peripherals: Integrated Micro USB for programming (CH340C), Boot & Reset tactile switches, and broken-out GPIO headers.

Design Highlights

  • Optimized high-frequency switching loops for the buck regulator to minimize EMI.
  • Completely isolated RF antenna keepout zone on both layers for maximum wireless signal integrity.
  • Solid ground planes on both layers for optimal return paths.
