Speaker pHAT Help - What pins does it really need


#1

I have a 40pin breakout cable on my Pi Zero W going to a breadboard.
I’d like to attach just the pins I really need to the Speaker pHAT for sound - I don’t need lights.
For alerts in my house, I’m trying to get better sound that some beeps from a Piezzo speaker.

So, of the 40 pins on the header, can someone tell me which pins I need?
thx

If you follow the link above you will see what pins the speaker phat uses. If you do not need the lights then there is no need to connect gpio 2 and 3 at the top of the header

Hope that helps!

Hi Will
Didn’t know about that site.
I tried just sending 4 wires from my Pi3 to my soldered header on Speaker Phat and had issues - so plugged it directly in and still had issues. Ive posted about that in another thread. Thx for helping!!!
