Philips-LivingColours-GEN2.jpeg - PCB from an old Philips LivingColours lamp which we have long since lost the remote for. Modified to work as part of my ESPHome setup. See key on image for the locations of the various control pins, I mounted a M5Stack Pico over the location the original CPU sat and ran wires to the 4 gpios for RED/GREEN/BLUE & Enable (as far as I can tell enables the powersupply section that feeds the LED's). I did try using the 3v feed that fed the microprocessor but it was not enough for the ESP32 to powerup. instead I used a mini buck converter with the inputs from a capacitor connected to the Power in port (18 Volts!!) which provided a 5v feed for the pico.

Questions
How big is the Esp32-s3-dev PCB?
It measures 46.6 × 32.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Esp32-s3-dev use?
48 parts, built around the ESP32-S3-WROOM-1-N8, AMS1117-3.3, LIS3DH and USBLC6-2SC6. 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 Esp32-s3-dev KiCad files?
From the shades66/OddsAndEnds repository on GitHub, at the commit this page was made from: the board is ESP32Boards/V2/esp32-s3-dev.kicad_pcb and its schematic ESP32Boards/ESP32-Pico-V2-MiniPICO/ESP32PICOV3.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Esp32-s3-dev design in my own project?
Its repository states no licence, so its author keeps all rights: ask shades66 before reusing the design.
