“Amazing performance, directly compatible with my GPIO-triggered video selection software written for the R-Pi3. Just swapped the SD card and it worked immediately. The only difference was the startup which seems to be a bit longer than the 3, and some small timing difference on multi-tasking (easily adjusted).”
“I bought it for a specific project I'm running Pi light and it performs better than I expected, onboard WIFI and bluetooth is a real bonus. My only quibble would be I would have liked to have been offered a headerless version but never spotted the option. As I suspected the pins got in the way and were fiddly to remove but nothing is impossible. Now all is well, running cool and working as I wanted.”
