CB-AUG21 £11.95 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. Back issues of articles are available – see Back Issues page for details. 68 Practical Electronics | May | 2023 Double-sided | plated-through holes | solder mask PROJECT JULY 2021 CODE PRICE ATtiny816 Breakout / Dev Board with Capacitive Touch.... 24110181 £9.75 IR Remote Control Assistant (Jaycar version).................... 15005201 £8.95 IR Remote Control Assistant (Altronics version)................ 15005202 £8.95 PIC18F Development Board..............................................
