Kassenautomat.mdb interface: common questions

What microcontroller does the Kassenautomat.mdb interface use?

The Kassenautomat.mdb interface is built around the ATMEGA644PA-A, from the AVR/Arduino family.

How big is the Kassenautomat.mdb interface PCB?

The Kassenautomat.mdb interface measures 100 × 100 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Kassenautomat.mdb interface?

69 components, from 35 distinct parts. The full bill of materials is listed on this page.

Where can I download the Kassenautomat.mdb interface design files?

From the fau-fablab/kassenautomat.mdb-interface repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Kassenautomat.mdb interface design in my own project?

The repository has no license, so all rights stay with fau-fablab. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Kassenautomat.mdb interface without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
