Elektroniikkapaja: common questions

What microcontroller does the Elektroniikkapaja use?

The Elektroniikkapaja is built around the ATMEGA644-20A, from the AVR/Arduino family.

How big is the Elektroniikkapaja PCB?

The Elektroniikkapaja measures 77 × 77 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Elektroniikkapaja?

72 components, from 49 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 Elektroniikkapaja design files?

From the ripaskajaska/Wireless-weather-station 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 Elektroniikkapaja design in my own project?

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

Can I test firmware for the Elektroniikkapaja 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.
