NoPour: common questions

What microcontroller does the NoPour use?

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

How big is the NoPour PCB?

The NoPour measures 45.7 × 66 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the NoPour?

68 components, from 25 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 NoPour design files?

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

Can I use the NoPour design in my own project?

Yes, under the terms of its MIT license, which plertvilai chose for the repository.

Can I test firmware for the NoPour 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.
