Dynamis: common questions

What microcontroller does the Dynamis use?

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

How big is the Dynamis PCB?

The Dynamis measures 9.1 × 18.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Dynamis?

198 components, from 40 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 Dynamis design files?

From the bbrfkr/dynamis-keyboard 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 Dynamis design in my own project?

Yes, under the terms of its MIT license, which bbrfkr chose for the repository.

Can I test firmware for the Dynamis 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.
