I've been working on a custom stereo I2S amplifier board using the MAX98357 IC. I've had the first version manufactured by PCBWay (https://www.pcbway.com/) and now I need to design version 2 - I'll get this manufactured by PCBWay again. 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. 0:00 Intro - what are we trying to do? 38:30 Why KiCad - what's so special about KiCad? 1:10 Geting KiCad setup for PCBWay 1:46 Adding a new symbol to KiCad for the MAX98357 2:38 Designing the schematic for our board 4:33 Assigning footprints to the symbols 5:18 Converting the schematic to a PCB 5:34 Using a DXF file to make a custom board outline 6:08 Laying out the PCB 6:52 Ground planes/Copper pours 7:13 3D Viewer and adding missing 3D models 7:41 3D Export for Fusion 360 8:07 Adding the mounting holes 8:48 Labelling the pins 9:03 Gerber Export 9:50 Creating the BOM file 10:40 Component positions 10:57 Order submission to PCBWay for manufacture and SMT assembly 11:20 Final costs and sanity check 11:43 What do I think of KiCad?

If you're tired of constantly buying new batteries for your LED light strings, this video is for you! As usual, we're sponsored by https://www.PCBWay.com/?from=atomic. We're going to hack our lights and make them rechargeable with just a few simple steps. We'll also bump up the resistance to get a bit more battery life - the lights are still bright enough, so it's pretty cool! Grab your soldering iron and let's get hacking! --- If you'd like to help support the channel then I have a Patreon page: https://www.patreon.com/atomic14 And if you're shopping on AliExpress or Amazon then if you click on these links I will get a little bit of affiliate money: Aliexpress - https://s.click.aliexpress.com/e/_Ac05mF Amazon - https://www.amazon.com/?tag=atomic14-20 You can also join us on Discord here: https://discord.gg/h2DDnDdjD2 And we've got an exciting new newsletter! https://makernews.substack.com/ ... https://www.youtube.com/watch?v=DO1chYoRB3Q
