Turn the red switch to the **right position** and then press the **red button** to the left side of the red switch to power the USB Hub Controller Chip otherse the keyboard **can't be used!** At the same time the indicator for the battery voltage will be turned on.   # <a name='Keyboard '>Keyboard </a> The keyboard type is blackberry Q10 or Q20 keyboard. Both have the same keyboard layout. There is a red switch on the left side to decide if the keyboard controller communicates with the HackberryPi or with other device through the USBC-Port underneath.
