CW-CONTROLLER: common questions

What microcontroller does the CW-CONTROLLER use?

The CW-CONTROLLER is built around the ATmega32U4, from the AVR/Arduino family.

How big is the CW-CONTROLLER PCB?

The CW-CONTROLLER measures 126 × 57 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the CW-CONTROLLER?

247 components, from 64 distinct parts. The full bill of materials is listed on this page.

Where can I download the CW-CONTROLLER design files?

From the prusa3d/CW-CONTROLLER-PCB repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the CW-CONTROLLER design in my own project?

The repository has no license, so all rights stay with prusa3d. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the CW-CONTROLLER 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.
