Handy PCB to modify equipment to use of USB-C instead of a bunch of random power adaptors.
(Note voltage markings on PCB silkscreen legend above are wrong)
Multiple holes are provided for various connection options - using ~0.8mm
tinned copper wire from both sides to go into the slots
for the powerjack connector is usually strong enough to not need any additional
support. Some epoxy can be used if more
support is needed. Long 0.1" pin header pins can also be used for strength.
