Syzygy breakout standard: common questions

What microcontroller does the Syzygy breakout standard use?

The Syzygy breakout standard is built around the ATTINY44A-MMH, from the AVR/Arduino family.

How big is the Syzygy breakout standard?

The Syzygy breakout standard measures 45 × 70 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Syzygy breakout standard?

10 components, from 8 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 Syzygy breakout standard design files?

From the butterstick-fpga/syzygy-breakout-standard 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 Syzygy breakout standard design in my own project?

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

Can I test firmware for the Syzygy breakout standard 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.
