From the biz I have a few boxes full of duds. If anyone wants to pay for shipping and $1 per piece. let me know. I have a few lcds as well.
I keep them around occasionally I take of components or experiment with them. The shields can be missing components,a bunch just have a bad mosfet, all sorts of random things that I couldn’t fix quickly. The megas sometimes will flash sometimes, sometimes just a bad pin, missing components, etc.
Most do not work at all.
If you want a specific component I can try and cherry pick but best to get two just in case one is bad. I can’t flash and test components so it is just an as is thing. I will do any visual checks you want.
