   2 # Config for using Raspberry Pi's expansion header
   3 #
   4 # This is best used with a fast enough buffer but also
   5 # is suitable for direct connection if the target voltage
   6 # matches RPi's 3.3V and the cable is short enough.

   8 # Do not forget the GND connection, pin 6 of the expansion header.
