MCL8080: common questions

What microcontroller does the MCL8080 use?

The MCL8080 is built around the ATtiny85V-10P, from the AVR/Arduino family.

How big is the MCL8080 PCB?

The MCL8080 measures 36.3 × 40.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the MCL8080?

10 components, from 6 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the MCL8080 design files?

From the MicroCoreLabs/Projects repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the MCL8080 design in my own project?

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

Can I test firmware for the MCL8080 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.
