ESP32-S3 for use with ESPHome
-
4 Open-Drain Channels for RGBW
-
2 Buttons for user input
-
WS2812 LED
-
Multiple headers for further peripherals (I2C, 3V3, 5V, GPIOs)
-
6V to 15V Input

Questions
How big is the Starfish PCB?
It measures 60 × 50 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Starfish use?
81 parts, built around the ESP32-S3-WROOM-1-N8, LM1117-3.3, LTV-817S and PMV40UN2R. 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 Starfish KiCad files?
From the paeber/led-driver-starfish repository on GitHub, at the commit this page was made from: the board is starfish/starfish.kicad_pcb and its schematic starfish/led-driver.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Starfish design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
