Amur leopard: common questions

What microcontroller does the Amur leopard use?

The Amur leopard is built around the ATmega32U4-AU, from the AVR/Arduino family.

How big is the Amur leopard PCB?

The Amur leopard measures 104.1 × 39.7 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Amur leopard?

32 components, from 13 distinct parts. The full bill of materials is listed on this page.

Where can I download the Amur leopard design files?

From the KingMalur/Keyboards repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Amur leopard design in my own project?

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

Can I test firmware for the Amur leopard 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.
