Desligador: common questions

What microcontroller does the Desligador use?

The Desligador is built around the ATmega328P-AU, from the AVR/Arduino family.

How big is the Desligador PCB?

The Desligador measures 76 × 62 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Desligador?

109 components, from 34 distinct parts. The full bill of materials is listed on this page.

Where can I download the Desligador design files?

From the carloslcor/Master_off repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Desligador design in my own project?

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

Can I test firmware for the Desligador 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.
