Sharpikeebo: common questions

What microcontroller does the Sharpikeebo use?

The Sharpikeebo is built around the ATmega32U4-MU, from the AVR/Arduino family.

How big is the Sharpikeebo PCB?

The Sharpikeebo measures 66 × 115.3 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Sharpikeebo?

190 components, from 108 distinct parts. The full bill of materials is listed on this page.

Where can I download the Sharpikeebo design files?

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

Can I use the Sharpikeebo design in my own project?

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

Can I test firmware for the Sharpikeebo 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.
