Questions
How big is the Mcu PCB?
It measures 100 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Mcu use?
168 parts, built around the ESP32-PICO-D4, HX711, TM1638 and FJ3461AH. 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 Mcu KiCad files?
From the cs2dsb/coffee_assistant repository on GitHub, at the commit this page was made from: the board is hardware/mcu/mcu.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Mcu design in my own project?
Its repository publishes it under the Apache-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
