Hi All,
I have a single board computer that outputs 3.3V on its GPIO port. The trouble is that a couple of the pins on the GPIO port are actually 5V and GND. My understanding was that the I/O would then be 5V/GNd logic not 3.3V. Does anyone have any ideas why this is?
When i measure from output to ground its 3.3V, but if i measure output to 5V i see 1.7V, why is this?
Thanks
