NQSAP Output Display: common questions

What microcontroller does the NQSAP Output Display use?

The NQSAP Output Display is built around the ATmega328P, from the AVR/Arduino family.

How big is the NQSAP Output Display PCB?

The NQSAP Output Display measures 102 × 96 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the NQSAP Output Display?

18 components, from 12 distinct parts. The full bill of materials is listed on this page.

Where can I download the NQSAP Output Display design files?

From the TomNisbet/nqsap-pcb repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the NQSAP Output Display design in my own project?

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

Can I test firmware for the NQSAP Output Display 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.
