Voltlog #214 – How bad is a fake apple lightning to 3.5mm audio adapter?

Welcome to a new voltlog, today we’re taking a look at these lightning to 3.5mm audio adapters that you have to use ever since apple removed the 3.5mm jack on the iphone. So you know the story, apple removed the jack and said it’s because they will free-up space inside the phone and it makes it more waterproof but if you ask me that’s bullshit, they removed it to force people to buy bluetooth headphones. But anyway we won’t go into that, this video is about the adapter that they now give people to still be able to use the 3.5mm jack for audio.

This made me wanna take a closer look so here are the two adapters, the plan is to connect a 3.5mm jack, this will provide me with some contacts where I can probe with the oscilloscope. I’m gonna generate a known constant waveform from an app and we’re going to measure that and compare between the two adapters.
