REVIUNG33: common questions

What microcontroller does the REVIUNG33 use?

The REVIUNG33 is built around the ATMEGA32U4-AU, from the AVR/Arduino family.

How big is the REVIUNG33 PCB?

The REVIUNG33 measures 197 × 75.2 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the REVIUNG33?

86 components, from 14 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 REVIUNG33 design files?

From the gtips/reviung repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the REVIUNG33 design in my own project?

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

Can I test firmware for the REVIUNG33 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.
