Rose: common questions

What microcontroller does the Rose use?

The Rose is built around the ATMEGA32U4, from the AVR/Arduino family.

How big is the Rose PCB?

The Rose measures 228.6 × 78 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Rose?

116 components, from 21 distinct parts. The full bill of materials is listed on this page.

Where can I download the Rose design files?

From the westfoxtrot/rose_pcb repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Rose design in my own project?

Yes, under the terms of its CC-BY-SA-4.0 license, which westfoxtrot chose for the repository.

Can I test firmware for the Rose 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.
