Digital Command Control (DCC) converter for Arduino and ESP32


DCC (Digital Command Controller) converter is a small circuit that transforms the DCC signal from rails into HIGH|LOW (0|1) that can be read by almost any MCU (Arduino boards, ESP32 boards, and others). The circuit also includes DCC/AC to DC converter and can be used to power layout elements with up to 20V and boards with MCU worked with 3.3V or 5V


  • Dimensions: 38mm x 18mm x 11mm
  • Transform DCC signal from rails into a digital signal that can be read by MCU (ESP32 boards, Arduino boards, and others)
  • Max total current: 1.5A
  • Power supply: 8-20V DCC / DC
  • 3 power outputs: 3.3V DC, 5V DC, 8-20V DC
  • The example schematic of how to use this circuit can be found at

The model is intended for modelers over 14 years of age.
