Katana60-pro: common questions

What microcontroller does the Katana60-pro use?

The Katana60-pro is built around the ATMEGA32U4-M, from the AVR/Arduino family.

How big is the Katana60-pro PCB?

The Katana60-pro measures 285 × 94.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Katana60-pro?

165 components, from 19 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 Katana60-pro design files?

From the rominronin/katana60-pro 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 Katana60-pro design in my own project?

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

Can I test firmware for the Katana60-pro 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.
