I've been working on a custom stereo I2S amplifier board using the MAX98357 IC. I've had the first version manufactured by [ Ссылка ] and now I need to design version 2 - I'll get this manufactured by PCBWay again.
PCBWay provide sponsorship for the channel that helps pay for components and software.
There's a couple of things I need to fix from my first design. I made the boards far too small (got carried away in the PCB layout stage and thought I was being clever). So I'm going to fix that in this version.
I always want to learn to use KiCad, so this feels like a good opportunity to do that.
