I'm building an open-source bio-research hardware (ask me how you can help!) and I've got this guy here:
My big questions are:
Can I get away with all the ground being common? (I've got a 12v and 5v needing to be grounded)
Do I need two sets of capacitors? There are 2 wired up to the 12v regulator and 2 wired to the 5v regulator. (These are shown in blue)
I've generally denoted connections which go UNDER the shield as orange, and those above as green.
If anyone happens to see something which might backfire, feel free to point it out. As this is also my first time making anything quite like this!
- I've verified the regulator positions and they are correct.
- This is a proto-shield for an Arduino R3 Uno.
