BlinkySWR: common questions

What microcontroller does the BlinkySWR use?

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

How big is the BlinkySWR PCB?

The BlinkySWR measures 34.5 × 26.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the BlinkySWR?

45 components, from 14 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 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 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 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.
