Questions
How big is the Control board PCB?
It measures 35 × 50 mm and has 4 copper layers, 1.61 mm thick.
What parts does the Control board use?
110 parts, built around the ESP32-C3, APDS-9306-065, DRV8871DDA and TPS562202DRL. 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 Control board KiCad files?
From the rijn/smart-blind-control repository on GitHub, at the commit this page was made from: the board is control_board/control_board.kicad_pcb and its schematic control_board/control_board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Control board 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).

This version was an attempt to use a 2S battery pack. The main issue is that as of 2022-09-15, there are not many 2S battery charging IC's nor a nice i2C fuel gauge IC, so at the moment, this is a dead end design.
