Prusa chain production: common questions
What microcontroller does the Prusa chain production use?
The Prusa chain production is built around the Arduino_pro_micro, from the AVR/Arduino family.
How big is the Prusa chain production PCB?
The Prusa chain production measures 55.9 × 76.2 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Prusa chain production?
18 components, from 11 distinct parts. The full bill of materials is listed on this page.
Where can I download the Prusa chain production design files?
From the d-weber/prusa-chain-production repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Prusa chain production design in my own project?
It is published under CC-BY-NC-4.0, which limits how it may be reused; read the license before building on it.
Can I test firmware for the Prusa chain production 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.
