EuroPowerSupply2

Maker	Johansen Engineering
Type	4HP power module converting a 19V laptop supply to plus and minus 12V and 5V
Mounting	Mixed
Width	4 HP
License	Proprietary (No licence published on this repo)
Difficulty	🔥 SMD (0805)

Faceplate takes the laptop barrel input and can be daisy chained to the next case. The README warns that some laptop supplies bond earth to the sleeve, which would land on minus 12V rather than ground in this circuit.
