2. Git clone the repository and place the file named "kratos" in the ~/ directory ( home directory )ORJust Run the code
4. Now run the kratos file from any terminal.
Type the Option and then hit Enter . Dont interefere / click while the automation is going one . It usually takes few second if the connections are ok .

Arm: common questions
How big is the Arm PCB?
The Arm measures 91.4 × 69 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Arm?
18 components, from 18 distinct parts. The full bill of materials is listed on this page.
Where can I download the Arm design files?
From the darkom3ga/Mark5 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Arm design in my own project?
The repository has no license, so all rights stay with darkom3ga. Use it as a reference, and ask the author before reusing the design.
