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, plated-through
hole, with 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.
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.
Back issues of articles are available – see Back Issues page for details.
