Motherboard headers availability

Let’s say I’d like to remove speakers and put in their place my custom DIY hardware.
Are any buses on the motherboard available to use (as headers)? like USB, I2S, LPC or GPIO?


There are debug headers in the top right corner, though the connectors are unpopulated. When we have a chance, we’ll publish pinouts for those (though this is very much not a supported path, and something that you’ll have to decide whether to take the risk around).


I believe you can use the regular speaker headers. Just find a connector that go into those.
