I just bought the

How can i connect 4 buttons and 4 leds to the board? I want to be able to control them from the esp32 micro controller. Are there any GPIO-'s free ? Which ones ?

What is the GPIO_D Digital and artificial I/O interface ? Can i use that one to connect buttons and leds ? And if yes, do i need extra hardware? What kind?

Thank you for your answers!
