Thicken tracks for Power #15

Closed mburger82 closed 1 year ago

Measurements of Voltage Regulators showed, they work very well. But over the length of the tracks the voltage gets lover up to 0.5V at higher currents. Need to thicken them and have multiple Vias on layer changes.

The automatic power selector seams to do something weird. Have to investigate.

changed fets of power switch circuitry to known values from Eduboard 1.0 (IRLML6402 and 2N7002) done in 6b6c116b6bcae3050ed2b55effb6c0dd89c6705c

3.3V is stable up to 2A 5V goes down to 4.7V@1A So 5V Lines have to be thicker and more direct!

Well... Voltage drop comes from mosfet RDSOn @ 80mOhm or so. At 1A this results in quite some Voltage. Good enough!
