REVIUNG34: common questions

What microcontroller does the REVIUNG34 use?

The REVIUNG34 is built around the ATMEGA32U4-AU, from the AVR/Arduino family.

How big is the REVIUNG34 PCB?

The REVIUNG34 measures 214.8 × 107.2 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the REVIUNG34?

89 components, from 10 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 REVIUNG34 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 REVIUNG34 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 REVIUNG34 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.
