I have since around 1 year done a smart room, where i made a custom pcb, and salvaged some parts from an old laptop motherboard to be able to control the LED strip that i have and also open and close my curtain, but…
It measures 100 × 150 mm and has 4 copper layers, 1.6 mm thick.
114 parts, built around the ESP32-S3-WROOM-1-N8, MAX3485ED, ADS1115IDGS and MT3608. 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.
From the loubnayesref/monitor- repository on GitHub, at the commit this page was made from: the board is monitor.kicad_pcb and its schematic CN3304_CHARGER.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask loubnayesref before reusing the design.
