Questions
How big is the DFPLAYER PCB PCB?
It measures 69.1 × 56.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the DFPLAYER PCB use?
62 parts, built around the ATMEGA328P-AU, CH340C, DFR0299 and DW01A. 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 DFPLAYER PCB KiCad files?
From the Erolctk/ATmega328P-DFPlayer-PCB repository on GitHub, at the commit this page was made from: the board is DFPlayer-PCB/KICAD/DFPLAYER_PCB.kicad_pcb and its schematic DFPlayer-PCB/KICAD/DFPLAYER_PCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the DFPLAYER PCB design in my own project?
Its repository states no licence, so its author keeps all rights: ask Erolctk before reusing the design.
