“This is an ideal board for simple expansion - I fitted ten temperature probes to my pi. The only suggestion is that it could be supplied with stand-offs (or the website could recommend you buy them at the same time).”
“This enabled me to knock up my own ADC pi hat as the available ones didn't have a fast enough sample rate. I expected the main part of the board to be like a matrix board where you can just join the dots up with solder to create tracks in any direction you wish, but they were already joined up in rows on the underside like a breadboard, not sure why this decision was made, it's rather limiting. Ended up having to cut some of the traces and using a lot more jumper cables to make the board.”
