CtLab: common questions

What microcontroller does the CtLab use?

The CtLab is built around the ATmega32-16M, from the AVR/Arduino family.

How many components are on the CtLab?

147 components, from 72 distinct parts. The full bill of materials is listed on this page.

Where can I download the CtLab design files?

From the MovGP0/ctLab repository on GitHub, which has the schematic; the links under Design files point to each one.

Can I use the CtLab design in my own project?

The repository has no license, so all rights stay with MovGP0. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the CtLab 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.
