Overview

Atmega8breakeout is an open-source printed circuit board by androiders, from the androiders/pcbs repository on GitHub. It is a 2-layer board with 12 parts on 29 nets, routed with 212 tracks and 4 vias.

It is built around the ATMEGA8L-8AU. Its parts include 4 connectors, 2 capacitors, 2 resistors, 1 IC and 1 diode. It belongs with the AVR (ATmega, ATtiny) boards of this library.

Ki-Cad

PCB layout:

Use as wide traces as possible. 1mm preffered.
Dont use "filled areas" if possible. It does not make good geometry in flatcam
Don't forget to set origin marker
Export gerber: use auxiliary axis

FlatCam

geometry generation:

If you are using thru-hole components or using bottom layer, mirror around y axis for both geometry and Drilling
Edit drill files if necessary for fewer drill sizes
TODO: test double sided layout by mirroring around center axis!

Isolation generation:

Current isolation mill depth to test: 0.04 mm (0.05 was tested and seems to work fine!) (Common copper depth is about 0.03 mm)
Current feedrate on isolation milling to test: 60 mm/s
spindle speed 12000 rpm
use 0.2 mm tool width on cnc generation
2 passes with 0.1 overlap

Cutout generation:

Current cutout mill depth: 1.6 mm
Current feedrate on cutout milling: 40 mm/s
spindle speed 12000 rpm

FlatCam defaults:

put a link in ~/.FlatCAM/defaults.json

Probe:

Drilling:

Current drill plunge rate to test 20 mm/s
spindle speed: 12000 rpm
Drill depth: 1.6

Questions

What parts does the Atmega8breakeout use?

12 parts, built around the ATMEGA8L-8AU. 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 Atmega8breakeout KiCad files?

From the androiders/pcbs repository on GitHub, at the commit this page was made from: the board is atmega8breakout/atmega8breakeout/atmega8breakeout.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Atmega8breakeout design in my own project?

Its repository states no licence, so its author keeps all rights: ask androiders before reusing the design.
