The schematic for the board is:
Where the components are as shown here:
Some points to note:
- The switch inputs (GPIO24 and GPIO23) would be set as pulled up inputs so that they would normally read HIGH and then go LOW when the button was pressed.
- The signal on GPIO4 to control the fan is a 3.3V signal whereas the fan needs a 5V supply to run at full speed.
- GPIO19 is one of the hardware PWM channels. The audio output also uses this so they can't be used at the same time.
