Nt660: common questions

What microcontroller does the Nt660 use?

The Nt660 is built around the ATmega32U4, from the AVR/Arduino family.

How big is the Nt660 PCB?

The Nt660 measures 312 × 96.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Nt660?

159 components, from 24 distinct parts. The full bill of materials is listed on this page.

Where can I download the Nt660 design files?

From the evyd13/nt-series repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Nt660 design in my own project?

Yes, under the terms of its CC-BY-SA-4.0 license, which evyd13 chose for the repository.

Can I test firmware for the Nt660 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.
