About the Master PCB

Master is an open source AVR/Arduino PCB design by cactorium, published on GitHub under the MIT license. It is a 2-layer board measuring 47.4 × 32.6 mm, with 45 components from 34 distinct parts.

Its main chip is the ATTINY24-SS, from the AVR/Arduino family. Other key parts include the ADP151AUJZ-3.3-R7, TM4C123GH6PM, RN-42, FGPMMOPA6H and SN74LV1T04. By type, the board carries 11 capacitors, 11 resistors, 7 ICs, 6 connectors, 2 transistors and 2 switches.

From the project

EEG software, alpha stages. Will be opensourced when it's working!

UCFBrainStuff ============= UCF senior design project, schematic files and other things. Will be open sourced at some point probably! All work is currently done in KiCAD but it may be converted to a different EDA software

Master design files

The KiCad project lives in the cactorium/UCFBrainStuff repository on GitHub; these links point at the commit this page was built from.

Master: common questions

What microcontroller does the Master use?

The Master is built around the ATTINY24-SS, from the AVR/Arduino family.

How big is the Master PCB?

The Master measures 47.4 × 32.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Master?

45 components, from 34 distinct parts. The full bill of materials is listed on this page.

Where can I download the Master design files?

From the cactorium/UCFBrainStuff repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Master design in my own project?

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

Can I test firmware for the Master 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.
