PCBs for most recent PE/EPE constructional projects are available. From the July 2013 issue onwards, PCBs with eight-digit codes
have silk screen overlays and, where applicable, are double-sided, have plated-through holes, and solder mask. They are similar to
photos in the project articles. Earlier PCBs are likely to be more basic and may not include silk screen overlay, be single-sided, lack
plated-through holes and solder mask.
Always check price and availability in the latest issue or online. A large number of older boards are listed for ordering on our website.
In most cases we do not supply kits or components for our projects. For older projects it is important to check the availability
of all components before purchasing PCBs.
Magazine back issues are available – see https://www.electronpublishing.com/product-category/pe-back-issues-print-and-digital/
