BlinkySWR-0.1: common questions

What microcontroller does the BlinkySWR-0.1 use?

The BlinkySWR-0.1 is built around the ATTINY13A-SSH, from the AVR/Arduino family.

How big is the BlinkySWR-0.1 PCB?

The BlinkySWR-0.1 measures 50.5 × 28.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the BlinkySWR-0.1?

44 components, from 19 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 BlinkySWR-0.1 design files?

From the bubnikv/BlinkySWR repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the BlinkySWR-0.1 design in my own project?

Yes, under the terms of its GPL-2.0 license, which bubnikv chose for the repository.

Can I test firmware for the BlinkySWR-0.1 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.
