Wasdat: common questions

What microcontroller does the Wasdat use?

The Wasdat is built around the ATMEGA32U4-AU, from the AVR/Arduino family.

How big is the Wasdat PCB?

The Wasdat measures 55.5 × 33 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Wasdat?

20 components, from 15 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 Wasdat design files?

From the evyd13/wasdat 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 Wasdat design in my own project?

Yes, under the terms of its CC-BY-SA-4.0 license, which evyd13 chose for the repository.

Can I test firmware for the Wasdat 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.
