Explorer Hat: Output measured at only 0.6V


I have just started using a standard explorer hat (not the pro) and I am measuring the output voltage and only measuring 0.6V between output and ground with no load on the pins other than the multimeter. I do measure 4.93V between 5V and GND. This of course is after setting the output to on:

import explorerhat


Any ideas?



The Explorer HAT uses the outputs as ground, so when the output is turned on, it will sink to ground. See here: https://github.com/pimoroni/explorer-hat/blob/master/documentation/GPIO-pins.md

So, you would use the 5V pins to power your load, and connect the ground to an output pin.

Hope this helps!
