Ss main board: common questions

What microcontroller does the Ss main board use?

The Ss main board is built around the ATTINY1616-MNR, from the AVR/Arduino family.

How big is the Ss main board?

The Ss main board measures 62.1 × 83.8 mm, has 4 copper layers and is 1.2 mm thick.

How many components are on the Ss main board?

63 components, from 33 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 Ss main board design files?

From the loopj/short-stack 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 Ss main board design in my own project?

It is published under SHL-2.1, which limits how it may be reused; read the license before building on it.

Can I test firmware for the Ss main board 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.
