Hi I hope you can help. Please excuse my ignorance on where to find the necessary wiring information I require for my first extension project.
I have a raspberry pi zero with an enviro phat attached and I’d like to extend the sensors and add a SGP30 gas sensor.
I’ve bought a proto bonnet mini extension and can physically connect the SGP30 to the bonnet with the enviro phat mounted on top using the appropriate GPIO 11mm header, however, I have no idea how to wire up the board. How do I figure out which pins are available (i.e. not used by the enviro phat) for the SGP30 so I can wire up the additional sensor?
