Very disappointed with the build quality, poor soldering has meant the power connection on the HAT board has fallen off rendering my £180 purchase inoperable! :-(
Do ye solder? Just beside the former usb micro jack is a spot for plain wires to be tacked in (marked + - 5v/2.5a).
Or power the pi directly and forgo the power switch.
USB micro connectors are flimsy. They do break.
