  • Has anyone ever found that the signs (‘+’ ‘-’) marked on this board are reversed?? I’ve burnt 2 Arduino boards due to this!! If you take a careful look, the square hole is aligned with the ‘+’ sign on the 3-pin side, which should actually be ‘-’. And if you test with a multi-meter, the tow positive hole are connected !!!

No public wish lists :(
