For our next Project14 project, we need to make a circuit board that can speed up programming of an ESP8266.
To design the board, we used the Open-Source software KiCad. This gave us an opportunity to do a deep dive tutorial on how to use the software.
Warning, this is long and nerdy, but it gives you everything you need to know to make your own PCB files for fabrication. We hope to inspire kids and parents to learn KiCad to make their own fabricated board of awesomeness.
