Stereo Audio with Single Speaker Setup
This setup uses both left and audio channel.
- Solder a wire from the PWM0-R pad to the Pi Zero’s GPIO18 pin or the Pi 3’s right audio from the headphone jack.
- Solder a wire from the PWM1-L pad to the Pi Zero’s GPIO13 pin or the Pi 3’s left audio from the headphone jack.
- Solder the volume pot to the board with their respective pins. You can use a 5-pin or a 3-pin volume wheel.
- Solder a wire from the S_R+ pad to the speaker’s positive(+) pin.
- Solder a wire from the S_R- pad to the speaker’s negative(-) pin.
- Last step is to combine both left and audio for the speaker by soldering a jumper wire from S_R+ pad to S_L+ pad.
- For Pi Zero build, edit the
/boot/config.txtand add the following line:
dtoverlay=pwm-2chan,pin=18,func=2,pin2=13,func2=4
You can also use 2 speakers for left and audio output if that’s what you want.
There are different ways to setup the audio on a Game Boy Zero/3 but this is the most common and easiest way to do so good luck and happy building!
Hello im having some trouble with A game boy zero build. i installed the sound plays out fine but its stuttering and when i push buttons on my gameboy zero it sorta freezing a bit during game and the buttons stop functioning for a bit and they im thinking it might be sound related issue
Hi, i have the same issue as charles. The game freezes as soon i push some buttons. Replaced already several times the silicone pads with aftermarket and original pads. Sometimes its better but still some buttons will freeze the game. Bought 2 x v2.0.01 and already swapped them over but the issue remains the same. Please help tinkerboy!
