I’m trying to read voltage using ADC on electric imp. When using the pin 1 and 2 I get correct values. If i’m using pin 5, 7, 8 or 9 I get a voltage near 2.9 or so…
I got this board and only soldered a stackable header on the pins 1 to 9 and 3.3 V an GND.
Do you have any clue on what it can be?
I found why.. I just checked the datasheet! duhh
