My concern here is that I blew another choplifter board by wiring ALL the GND and +5v leads at the same time, so I had 4 gnd, 4 +5v and when I plugged it in, there was a pop and nothing happened. I can't afford to cook another board here. This time I only wired 1 line to the ground and 1 line to the 5v. I already plugged it in briefly at like +4v and the LED on the board didn't light. I'm afraid to burn a second board here.
