Proto-8: common questions

What microcontroller does the Proto-8 use?

The Proto-8 is built around the Teensy_3.2, from the NXP family.

How big is the Proto-8 PCB?

The Proto-8 measures 254 × 127 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Proto-8?

363 components, from 83 distinct parts. The full bill of materials is listed on this page.

Where can I download the Proto-8 design files?

From the marshalltaylorSFE/Proto-8 repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Proto-8 design in my own project?

Yes, under the terms of its MIT license, which marshalltaylorSFE chose for the repository.

Can I test firmware for the Proto-8 without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug NXP firmware against it before you order a PCB.
