Interrupter: common questions

What microcontroller does the Interrupter use?

The Interrupter is built around the ATTINY85-20PU, from the AVR/Arduino family.

How big is the Interrupter PCB?

The Interrupter measures 79.3 × 97 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Interrupter?

80 components, from 33 distinct parts. The full bill of materials is listed on this page.

Where can I download the Interrupter design files?

From the profdc9/DRSSTC-PCB-Pack repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Interrupter design in my own project?

The repository has no license, so all rights stay with profdc9. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Interrupter 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.
