全屋双色温灯光控制方案
这目前是设想中的方案，还未落地，因为水电还没弄好，卡住了。
仓库的大头目前是灯光控制板的设计。这类东西现成产品要么太贵，要么不符合要求，而且设计起来对AI来说算不上特别特别难的事情。按照设计预期，这块板应该能带动24V 12A 6路双色温的LED灯。设计完之后拿去嘉立创打样。

Questions
How big is the Cct main PCB?
It measures 130 × 164 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Cct main use?
217 parts, built around the 74HCT245PW, ESP32-WROOM-32E-N4, CH340C and INA237AIDGSR. 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 Cct main KiCad files?
From the syncmeta/PendingHome repository on GitHub, at the commit this page was made from: the board is cct-driver/hardware/cct-main.kicad_pcb and its schematic cct-driver/hardware/cct-main.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Cct main 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).
