Questions

How big is the AVR Datalogger PCB?

It measures 48.5 × 43.4 mm and has 4 copper layers, 1.6 mm thick.

What parts does the AVR Datalogger use?

29 parts, built around the ATMEGA328P-AU and DS1337S+T&R. 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 AVR Datalogger KiCad files?

From the 5a7man/PCBs repository on GitHub, at the commit this page was made from: the board is AVR_Datalogger/AVR_Datalogger.kicad_pcb and its schematic AVR_Datalogger/AVR_Datalogger.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the AVR Datalogger design in my own project?

Its repository states no licence, so its author keeps all rights: ask 5a7man before reusing the design.
