I’m looking to make a low power tiny arcade machine with a pi zero running retropie, and ordered a cheap LCD yesterday… As the GPIO on the screen takes up most of the physical space, I’m wondering if the remaining GPIO pins would accommodate a small 3.5mm interface for audio-out… Below are the screen I bought and the audio module I’m considering using.
! LCD module Pi TFT 3.5 inch (320*480) Touchscreen Display Module TFT for Raspberry Pi 3
Interface I2S PCM5102 DAC Decoder GY-PCM5102 I2S Player Module For Raspberry Pi pHAT Format Board Digital PCM5102A Audio Board
Example of interface
I know a lot of peeps would suggest not using a pi zero but this is a genuine experiment/project I’m hoping to learn from… So far I’ve considered (if I have enough correct unused pins remaining) instead of using a gpio socket strip, maybe use individual gpio cables to use the least possible space.
Hope y’all can help! Thanks
