Cherrycount: common questions

What microcontroller does the Cherrycount use?

The Cherrycount is built around the Arduino_Leonardo, from the AVR/Arduino family.

How big is the Cherrycount PCB?

The Cherrycount measures 97.1 × 91.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Cherrycount?

24 components, from 11 distinct parts. The full bill of materials is listed on this page.

Where can I download the Cherrycount design files?

From the AresEnsea/CDR2022_23 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Cherrycount design in my own project?

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

Can I test firmware for the Cherrycount 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.
