Questions
How big is the Fred v3 PCB?
It measures 284.2 × 102.8 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Fred v3 use?
243 parts, built around the SN65HVD230D, MCS1802GS-30-Z, PAC1921-1-AIA-TR and AMS1117-3.3. 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 Fred v3 KiCad files?
From the AMR-Frederico/Fred_PCB repository on GitHub, at the commit this page was made from: the board is fred_v3/fred_v3.kicad_pcb and its schematic Fred_PCB_testes/FPCB_Teste/Esp.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Fred v3 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).
