Internally Connected GPIO
Posted: Sat Jul 07, 2018 2:11 pmIve got a problem with two ESP-12N Boards I just got. I soldered them up to a board I designed and it seems that the GPIO 16, 14 and 12 are all connected internally on one board and on the other board it is just the GPIO 14 and 12. Is this common occurrence and how could I go about fixing it?
GPIO 14 and 12 are connected to a ULN2003AD to run a stepper motor in both cases. I tested the internally connected theory by turning one of the pins off in the code but its still giving me a problem, is this a bad board or can it be fixed?
Edit, was a soldering problem with solder paste, just make sure to go over each pin with a hotter iron.
