About the UserInterface PCB

UserInterface is an open source AVR/Arduino PCB design by LOEWE-emergenCITY, published on GitHub. It is a 2-layer board measuring 100 × 100 mm, with 19 components from 14 distinct parts.

Its main chip is the ATmega32-16A, from the AVR/Arduino family. Other key parts include the slice_connector_male. By type, the board carries 8 resistors, 3 connectors, 2 ICs, 2 capacitors, 1 transistor and 1 switch.

It belongs with the iot & wireless designs in this gallery.

From the project

The modular, research-friendly smart home hub

For developing we used KiCAD which is an open source CAD software. It was used by the Raspberry Pi Foundation for their IO Board and the Compute Module.

ONLY store files we already build. First step will only have project and schematics!

Each subdir is a stand alone KiCAD project.

The top level project is - for referencing the different schematics - showing the dependencies between the different PCBs - documentation - generating a full bill of material

UserInterface design files

The KiCad project lives in the LOEWE-emergenCITY/freespeaker repository on GitHub; these links point at the commit this page was built from.

UserInterface: common questions

What microcontroller does the UserInterface use?

The UserInterface is built around the ATmega32-16A, from the AVR/Arduino family.

How big is the UserInterface PCB?

The UserInterface measures 100 × 100 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the UserInterface?

19 components, from 14 distinct parts. The full bill of materials is listed on this page.

Where can I download the UserInterface design files?

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

Can I use the UserInterface design in my own project?

The repository has no license, so all rights stay with LOEWE-emergenCITY. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the UserInterface 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.
