Questions
How big is the RGB clock shield PCB?
It measures 68.6 × 53.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the RGB clock shield use?
18 parts, built around the ESP32-S3 and DS1307+. 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 RGB clock shield KiCad files?
From the TechTalkies/YouTube repository on GitHub, at the commit this page was made from: the board is 31 Custom Arduino Shield/RGB clock shield/RGB clock shield.kicad_pcb and its schematic 31 Custom Arduino Shield/RGB clock shield/RGB clock shield.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the RGB clock shield design in my own project?
Its repository states no licence, so its author keeps all rights: ask TechTalkies before reusing the design.
