I often have small numbers of PC boards left behind from earlier projects, because there was a fixed order quantity of 10 (which was still cost-effective). This page is a way to pass those extra boards on to any other experimenters who may find them useful.
Prices will be minimal (largely overheads and postage) but support will be minimal too – usually just a blog article with a circuit diagram and perhaps a parts list. Most will also involve SMD construction.
