Electronics projects: common questions

What microcontroller does the Electronics projects use?

The Electronics projects is built around the Arduino_Nano_Every, from the AVR/Arduino family.

How big is the Electronics projects PCB?

The Electronics projects measures 85 × 43.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Electronics projects?

124 components, from 5 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 Electronics projects design files?

From the mirmisbahali/electronics_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 Electronics projects design in my own project?

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

Can I test firmware for the Electronics projects 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.
