Lab 1 Building a Power Supply
Building A Power Supply
This is a PCB for supplying 3.3 or 5V to a breaboard at either 1 or 3A.
PCB, lots of surface mount components
The heatgun was used to solder most of the components to the board as
well as using an iron for specific dip and some surface mouhnt
components. The finished board can be seen below in Figure 1.

board was then tested but no voltage was observed at either terminals.
The diodes were discovered to be backwards but this didn't fix the
issue of the power never reaching the terminals. I was unable to find a
fix to this issues since the currect power was exiting all IC chips and
no components were getting hot after fixing the diodes. The final thing
I tested was continuity probing and everthing appeared to have the
proper continuity except for the final out pins so it seems like they
are for some reason disconnected.
