Questions
How big is the EEZ BB3 CM4 R1B0 PCB?
It measures 249.5 × 95 mm and has 4 copper layers, 1.6 mm thick.
What parts does the EEZ BB3 CM4 R1B0 use?
251 parts, built around the DP83848CVV/NOPB, TPD4E001DRLR, AT24C256C-SSHL-B and IS42S16400J-5BL. 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 EEZ BB3 CM4 R1B0 KiCad files?
From the intergalaktik/bb3-cm4 repository on GitHub, at the commit this page was made from: the board is EEZ_BB3_CM4_R1B0/EEZ_BB3_CM4_R1B0.kicad_pcb and its schematic EEZ_BB3_CM4_H7/Ethernet_PHY,_Audio,_DACs.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the EEZ BB3 CM4 R1B0 design in my own project?
Its repository states no licence, so its author keeps all rights: ask intergalaktik before reusing the design.
