Sit stand: common questions

What microcontroller does the Sit stand use?

The Sit stand is built around the ATMEGA328PB-AU, from the AVR/Arduino family.

How big is the Sit stand PCB?

The Sit stand measures 158.8 × 50.8 mm, has 2 copper layers and is 1.6002 mm thick.

How many components are on the Sit stand?

63 components, from 22 distinct parts. The full bill of materials is listed on this page.

Where can I download the Sit stand design files?

From the moonfall/sit-stand repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Sit stand design in my own project?

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

Can I test firmware for the Sit stand 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.
