Quantizer: common questions

What microcontroller does the Quantizer use?

The Quantizer is built around the ATtiny416-S, from the AVR/Arduino family.

How big is the Quantizer PCB?

The Quantizer measures 25 × 200 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Quantizer?

38 components, from 19 distinct parts. The full bill of materials is listed on this page.

Where can I download the Quantizer design files?

From the telec16/modular-synth 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 telec16. 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.
