Myfirstmacropad: common questions

What microcontroller does the Myfirstmacropad use?

The Myfirstmacropad is built around the ATmega32U4-AU, from the AVR/Arduino family.

How big is the Myfirstmacropad PCB?

The Myfirstmacropad measures 139.7 × 69.9 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Myfirstmacropad?

61 components, from 21 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 Myfirstmacropad design files?

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

Can I use the Myfirstmacropad design in my own project?

Yes, under the terms of its CC-BY-SA-4.0 license, which eeble chose for the repository.

Can I test firmware for the Myfirstmacropad 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.
