CustomKeeb2: common questions

What microcontroller does the CustomKeeb2 use?

The CustomKeeb2 is built around the ATMEGA32U4-A, from the AVR/Arduino family.

How big is the CustomKeeb2 PCB?

The CustomKeeb2 measures 309.6 × 100 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the CustomKeeb2?

150 components, from 79 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 CustomKeeb2 design files?

From the Goblnn/CustomKeeb2 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 CustomKeeb2 design in my own project?

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

Can I test firmware for the CustomKeeb2 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.
