Supported hardware

Microcontrollers

• Dahl Design CB1

• Atmel 32U4 (Pro Micro, Leonardo, Feather, Micro, Yùn, and many more)

• Atmel SAM3X8E* (Arduino Due or similar)

• Atmel SAMD21* (Zero, MKR Zero, M0, SAMD21 Mini)

• Atmel SAMD51* (Adafruit Metro M4)

• Raspberry Pi RP2040 (Raspberry Pi Pico, Pro Micro RP2040, Feather RP2040, and many more)

*These microcontrollers currenly dont have LED support.

Switches

• Most, if not all, commonly used switches in sim racing DIY. That goes for multiposition switches, rotary switches, encoders, buttons, toggles, potentiometers, hall sensors, etc.

If you have a switch that doesnt work with DDC, make an issue rapport and I'll add support.

LED

• Any addressable RGB (not RGBW) LED that is supported by the Adafruit Neopixel library.

• Analog LEDs using PWM or digital output.

Integrated circuits

• Shift registers

  • 74HC165

  • 74HC166

  • Other 8-bit parallell in/serial out shift registers might work.

• Port expanders

  • PCA9555

• ADC (analog to digital converter)

  • ADS1115

• EEPROM

  • CAT24C512

Circuit control

• Controlling other circuits, DC motors and more using PWM.
