Questions
How big is the FKECL AVR-51 PCB?
It measures 110 × 95 mm and has 2 copper layers, 1.6 mm thick.
What parts does the FKECL AVR-51 use?
82 parts, built around the STC89C52RC-40I, MAX232N, DS18B20 and S8550. 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 FKECL AVR-51 KiCad files?
From the mkhuthir/pcb repository on GitHub, at the commit this page was made from: the board is fkecl_avr_51/FKECL-AVR-51.kicad_pcb and its schematic ATtiny104XNANOaddon/ATtiny104XNANOaddon.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the FKECL AVR-51 design in my own project?
Its repository publishes it under the BSD-2-Clause licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
