Smd class: common questions
What microcontroller does the Smd class use?
The Smd class is built around the ATTINY85-20SU, from the AVR/Arduino family.
How big is the Smd class PCB?
The Smd class measures 30 × 30 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Smd class?
16 components, from 14 distinct parts. The full bill of materials is listed on this page.
Where can I download the Smd class design files?
From the ep-infosec/50_google_makerspace-partsbin repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Smd class design in my own project?
Yes, under the terms of its CC-BY-4.0 license, which ep-infosec chose for the repository.
Can I test firmware for the Smd class 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.
