Questions
How big is the Stc89c52 PCB?
It measures 85 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Stc89c52 use?
39 parts, built around the STC89C52RC-40I, ADC0832CCN, CH343P and DS18B20. 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 Stc89c52 KiCad files?
From the ErBWs/DHU-STC51 repository on GitHub, at the commit this page was made from: the board is 2. Heater/3. PCB/stc89c52.kicad_pcb and its schematic 2. Heater/3. PCB/stc89c52.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Stc89c52 design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
