About the Controller PCB

Controller is an open source AVR/Arduino PCB design by domenipavec, published on GitHub under the MIT license. It is a 2-layer board measuring 90 × 30 mm, with 7 components from 6 distinct parts.

Its main chip is the ATTINY841-SSU, from the AVR/Arduino family. Other key parts include the 74LS138. By type, the board carries 3 capacitors, 2 ICs and 2 connectors.

Controller: common questions

What microcontroller does the Controller use?

The Controller is built around the ATTINY841-SSU, from the AVR/Arduino family.

How big is the Controller PCB?

The Controller measures 90 × 30 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Controller?

7 components, from 6 distinct parts. The full bill of materials is listed on this page.

Where can I download the Controller design files?

From the domenipavec/avr-snow repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Controller design in my own project?

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

Can I test firmware for the Controller 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.
