Questions

How big is the LFR ATMega4808 V2 PCB?

It measures 70.5 × 90 mm and has 2 copper layers, 1.6 mm thick.

What parts does the LFR ATMega4808 V2 use?

74 parts, built around the ATMEGA4808-AF and MJTP1230. 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 LFR ATMega4808 V2 KiCad files?

From the peterladur/ENMT221-PCB-Design repository on GitHub, at the commit this page was made from: the board is PCB_V2/_restore_backup_2026-09-20T15-57-53-347/LFR_ATMega4808_V2.kicad_pcb and its schematic PCB_V1/LFR_ATMega4808.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the LFR ATMega4808 V2 design in my own project?

Its repository states no licence, so its author keeps all rights: ask peterladur before reusing the design.
