Power
https://rc2014.co.uk/backplanes/backplane-pro/
Powered from a USB adapter via the barrel jack, in which case a jumper will need to be fitted across the ‘5v power’ link.
On the board for a 7805 regulator (or more efficient 7805 compatible switch mode regulator) and capacitors if you wish to run from a higher voltage and convert to 5v locally.
