Protocol seven: common questions

What microcontroller does the Protocol seven use?

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

How big is the Protocol seven PCB?

The Protocol seven measures 405.1 × 166.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Protocol seven?

259 components, from 14 distinct parts. The full bill of materials is listed on this page.

Where can I download the Protocol seven design files?

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

Can I use the Protocol seven design in my own project?

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

Can I test firmware for the Protocol seven 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.
