About the Quantizer PCB

Quantizer is an open source AVR/Arduino PCB design by Quinienl, published on GitHub. It is a 2-layer board measuring 30 × 100 mm, with 38 components from 25 distinct parts.

Its main chip is the Arduino_Mini_02_Socket, from the AVR/Arduino family. Other key parts include the MCP4821 and L7805. By type, the board carries 11 resistors, 10 diodes, 7 capacitors, 5 connectors, 2 ICs and 1 switch.

From the project

A MCP4821 version of Hagiwo Quantizer

This is a version of Hagiwo Quantizer with a MCP4821 12 bit DAC. The code is still under review. Using the new DAC I have to check calibration.

Quantizer: common questions

What microcontroller does the Quantizer use?

The Quantizer is built around the Arduino_Mini_02_Socket, from the AVR/Arduino family.

How big is the Quantizer PCB?

The Quantizer measures 30 × 100 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Quantizer?

38 components, from 25 distinct parts. The full bill of materials is listed on this page.

Where can I download the Quantizer design files?

From the Quinienl/Hagiwo-Quantizer repository on GitHub, which has the KiCad layout; 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 Quinienl. 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.
