- # Config for using Raspberry Pi's expansion header
- #
- # This is best used with a fast enough buffer but also
- # is suitable for direct connection if the target voltage
- # matches RPi's 3.3V and the cable is short enough.
- #
- # Do not forget the GND connection, pin 6 of the expansion header.
