Welcome to Boardsort™ - Learn - Sell - Profit -

The first picture has front and back of two boards - one at left and one at right. I think that the right board easily qualifies as peripheral. I am not sure about the one at left.

The second photo has two boards that I think will be peripheral. Can the socketed chips be removed from the top board?

The one on the right will make it to peripheral. Decent IC population for the size, and a sandwich (multi layer) board should push it in.
The one on the left... grr. I’ll go with just barely based on track pad boards being peripheral.

Wicked kool. That’s an AM30a1 controlling the switch. Not expensive: but an interesting idea. I’m missing the clock at first glance so my guess is they are using the cycles to time the frequency. This is what I love about being here: seeing the weird ways people cut corners in design to save money.
Sorry: peripheral. Leave the ICs. There’s a lot of waste weight here and the ICs should push it over the edge.
