REVIUNG34-SPLIT-LEFT: common questions

What microcontroller does the REVIUNG34-SPLIT-LEFT use?

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

How big is the REVIUNG34-SPLIT-LEFT PCB?

The REVIUNG34-SPLIT-LEFT measures 100 × 100 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the REVIUNG34-SPLIT-LEFT?

39 components, from 5 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-SPLIT-LEFT 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-SPLIT-LEFT 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-SPLIT-LEFT 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.
