I have many different iterations of boards from the same model of barcode scanners. I'm thinking they're high grade peripheral, but am unsure. I also have some other small boards from these scanners, but will be putting them in a separate post to keep things tidy.

I'm new to e-waste of this caliber and any help is appreciated!

I'm not sure what those large black boxes are on the 1st and 2nd iterations and how they would affect the grade. I would lean low telco at best; but again not sure.

The 3rd and 4th are likely high telco with all the chips and gold pins.

Those black boxes are some type of capacitor.

With a multiple Farad and 2.5v rating, those are most certainly super capacitors.. The black boxes..

I'm really not sure. Looking at the pictures again there may be some population under those capacitors as well. It could be low telco but if the capacitors and the iron bits weigh enough it might drop to high peripheral.
