Nemo: common questions

What microcontroller does the Nemo use?

The Nemo is built around the ATMEGA328P-AU, from the AVR/Arduino family.

How big is the Nemo PCB?

The Nemo measures 69.7 × 24.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Nemo?

20 components, from 17 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 Nemo design files?

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

Can I use the Nemo design in my own project?

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

Can I test firmware for the Nemo 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.
