Rakennus60: common questions

What microcontroller does the Rakennus60 use?

The Rakennus60 is built around the ATMEGA32U4-M, from the AVR/Arduino family.

How big is the Rakennus60 PCB?

The Rakennus60 measures 285.5 × 95 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Rakennus60?

144 components, from 20 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Rakennus60 design files?

From the rakennus/rakennus60 repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Rakennus60 design in my own project?

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

Can I test firmware for the Rakennus60 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.
