Scrap Boards
DD-08477 RoHS Compliant

Description: Let our failure be your creation. We've got quite a stack of coasters - these are PCBs that were retired because of hardware revisions and board changes. Probably because we never could get the board to work in the first place. So please, use these for any project you can think of - art, solder practice, drink coasters, etc. We look forward to giving them a happy home.

Price per board. Board varies in size and shape from 1x1" to 4x4". It's a grab bag - we can't say for sure what you'll get.

We cannot accept requests, returns, exchanges, provide documentation, or provide support on any aspect of these boards.
