Cat ball: common questions

What microcontroller does the Cat ball use?

The Cat ball is built around the ATMEGA328P-AU, from the AVR/Arduino family.

How big is the Cat ball PCB?

The Cat ball measures 35 × 34.7 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Cat ball?

31 components, from 8 distinct parts. The full bill of materials is listed on this page.

Where can I download the Cat ball design files?

From the zyyan20h/PCBRenewal repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Cat ball design in my own project?

The repository has no license, so all rights stay with zyyan20h. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Cat ball 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.
