Quantizer: common questions

What microcontroller does the Quantizer use?

The Quantizer is built around the Arduino_Nano_v3.x, from the AVR/Arduino family.

How big is the Quantizer PCB?

The Quantizer measures 50 × 100 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Quantizer?

105 components, from 26 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 Quantizer design files?

From the QuinnFreedman/modular 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 Quantizer design in my own project?

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

Can I test firmware for the Quantizer 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.
