5 FAQ

Q: Does this board support Arduino IDE libraries?

A: While primarily for STM32Cube, community ports for Arduino exist but are not officially supported.

Q: What is the maximum current per digital output channel?

A: Each digital output supports up to 2A for relay outputs depending on the load.

Q: Is the 24V power input electrically isolated?

A: Yes, the power input features optocoupler isolation for safety and noise reduction.

Q: Can I program this via USB directly?

A: You will need an ST-Link V2 programmer connected to the SWD pins on the board.

Q: Which IDE is recommended for programming this board?

A: STM32CubeIDE or Keil MDK are fully supported for development.
