I have a need for a shield for my DIY aquarium doser project. The unit runs on the particle photon, and they do not offer a MOSFET shield, only a mechanical relay shield, so I thought I'd try to build one. The hard part for me is that the shield needs to supply power for the photon (5v) and for the pumps (12v) with a maximum of 1.2amps. I have the schematic for the voltage regulator Particle uses on their mechanical relay shield, but what I'm unsure of is if it will be cost efficient for me to order a very small number of boards with pre-soldered SMD components or if it would be better to go with a dual output Mean Well switching power supply.
I've attached the schematic of the power supply, as well the schematic (forgive me if its not good, its my first schematic) I created for the 4-switch N-Channel Mosfet board.
As always, I appreciate everyones help.
Thanks!
Dustin
