Questions

How big is the RELAY MODULE PCB?

It measures 63.5 × 59 mm and has 2 copper layers, 1.6 mm thick.

What parts does the RELAY MODULE use?

11 parts, built around the ESP32-WROOM-32, AMS1117 and BC547. 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 RELAY MODULE KiCad files?

From the Shyamjith-K/PCB_Assignment repository on GitHub, at the commit this page was made from: the board is RELAY MODULE.kicad_pcb and its schematic RELAY MODULE.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the RELAY MODULE design in my own project?

Its repository states no licence, so its author keeps all rights: ask Shyamjith-K before reusing the design.
