Overview
BarebonesAVR PCB is an open-source printed circuit board by adoble, from the adoble/BarebonesAVR-PCB repository on GitHub. It is a 2-layer board of 49 × 24.9 mm with 14 parts on 31 nets, routed with 399 tracks and 43 vias.
It is built around the ATMEGA328-AU. Its parts include 5 capacitors, 2 resistors, 2 connectors, 1 IC and 1 switch. It belongs with the AVR (ATmega, ATtiny) boards of this library.
Main components
1README
README.mdBarebonesAVR
A basic ATMega328P circuit that can be programmed with:
- an AVR programmer over a 6 pin ISP connection
- if the ATMega328P has an Arduino bootloader already loaded, then over an FTDI connection
The KiCAD files are stored under kicad.
Circuit
The circuit is for a TQFB package (SMD).

Questions
How big is the BarebonesAVR PCB PCB?
It measures 49 × 24.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the BarebonesAVR PCB use?
14 parts, built around the ATMEGA328-AU. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the BarebonesAVR PCB KiCad files?
From the adoble/BarebonesAVR-PCB repository on GitHub, at the commit this page was made from: the board is kicad/BarebonesAVR-PCB/BarebonesAVR-PCB.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the BarebonesAVR PCB design in my own project?
Its repository states no licence, so its author keeps all rights: ask adoble before reusing the design.
