Sherie: common questions

What microcontroller does the Sherie use?

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

How big is the Sherie PCB?

The Sherie measures 278.3 × 81.9 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Sherie?

117 components, from 23 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 Sherie design files?

From the flora495/Sherie 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 Sherie design in my own project?

The repository has no license, so all rights stay with flora495. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Sherie 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.
