Main board S8S1: common questions

What microcontroller does the Main board S8S1 use?

The Main board S8S1 is built around the ATtiny25-20SSU, from the AVR/Arduino family.

How big is the Main board S8S1?

The Main board S8S1 measures 114.3 × 86.4 mm, has 2 copper layers and is 1.5 mm thick.

How many components are on the Main board S8S1?

43 components, from 16 distinct parts. The full bill of materials is listed on this page.

Where can I download the Main board S8S1 design files?

From the Adept666/attiny25-45-85_development_kit repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Main board S8S1 design in my own project?
