Please can someone advise me how I can connect a Max98306 stereo amplifier to a raspberry pi 3 B+ or raspberry pi zero to get sound to output to a small speaker I have connected to the amp? Can I use the GPIO pins, if so which ones and how to I configure them? I have a small 4 OHM speaker and was …

That amplifier is analog in analog out. I used the following to connect my Pi’s analog audio out to it. [image] Right-Angle 3.5mm Stereo Plug to Pigtail Cable One of the most common converter cables you'll want in your cable collection - this 32" long cable converts a standard 3.5mm ster…

Thank you very much for your reply, this helps me understand a bit. First of all it looks like as the amp I have is analog in presumably I cant use the GPIO pins to provide input. Unfortunately this pigtail cable would not be suitable for my project but presumably I could solder 3 wires to the headp…

It’s all digital outputs on the GPIO. There are lots of DAC boards that plug onto the Pi’s GPIO and will drive speakers with an analog signal. Stuff like the pHat Beat and Pirate Audio line.

For anyone interested I found the info I needed. PP6 is the ground PP25 is left audio channel PP26 is the right audio channel I soldered wires on these points on the underside of the pi and connected them to the amp:- PP6 to L- and R- PP25 to R+ PP26 to L+ Connected power to the amp and voil…

I used a dual logarithmic potentiometer, 100k I believe. I wired it between the Pi’s output and the amps input. [image]

Actually, it looks like the one I used was 10k, not 100k. [image] Panel Mount 10K Dual Log Potentiometer This Panel Mount 10K Dual Log Potentiometer is a dual-ganged potentiometer that will satisfy all your stereo-signal needs. Instead of just one potentiometer, you actually get two sepa…
