Why I Designed This Project:
I began this project because I am getting a new large table built in my room and would love some LED lighting under it. I decided to make myself an LED controller with a lot of features. Most importantly, I wanted to have it be compatible with Alexa to match the other lights in my room. After a quick search, I found that the WLED firmware accomplishes all that I want: it is feature-rich, Alexa compatible, and supports custom ESP32 boards. And so, I embarked on a quest to make the most feature-packed LED controller to exist.

Questions
How big is the Blynk PCB?
It measures 80.5 × 53.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Blynk use?
110 parts, built around the ATTINY1616-SN, ESP32-S3-WROOM-1-N8, ES7243 and TPS563201. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Blynk KiCad files?
From the DynamicWhiteHat/Blynk repository on GitHub, at the commit this page was made from: the board is CAD/PCB/Blynk.kicad_pcb and its schematic CAD/PCB/Blynk.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Blynk design in my own project?
Its repository states no licence, so its author keeps all rights: ask DynamicWhiteHat before reusing the design.
