About the IEEE-Sign PCB

IEEE-Sign is an open source AVR/Arduino PCB design by kpzip, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 330 × 130 mm, with 159 components from 16 distinct parts.

Its main chip is the ATMEGA32U2-AUR, from the AVR/Arduino family. Other key parts include the LP2901D. By type, the board carries 96 capacitors, 47 diodes, 9 resistors, 2 ICs, 2 connectors and 2 switches.

Sign for the IEEE Lab

It's a sign that says "IEEE" using Argb lights. I don't know what more to say.

IEEE-Sign: common questions

What microcontroller does the IEEE-Sign use?

The IEEE-Sign is built around the ATMEGA32U2-AUR, from the AVR/Arduino family.

How big is the IEEE-Sign PCB?

The IEEE-Sign measures 330 × 130 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the IEEE-Sign?

159 components, from 16 distinct parts. The full bill of materials is listed on this page.

Where can I download the IEEE-Sign design files?

From the kpzip/IEEE-Sign repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the IEEE-Sign design in my own project?

Yes, under the terms of its GPL-3.0 license, which kpzip chose for the repository.

Can I test firmware for the IEEE-Sign 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.
