Morse-Code-LED-Blinker: common questions

What microcontroller does the Morse-Code-LED-Blinker use?

The Morse-Code-LED-Blinker is built around the ATtiny13A, from the AVR/Arduino family.

How big is the Morse-Code-LED-Blinker PCB?

The Morse-Code-LED-Blinker measures 40 × 40 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Morse-Code-LED-Blinker?

8 components, from 8 distinct parts. The full bill of materials is listed on this page.

Where can I download the Morse-Code-LED-Blinker design files?

From the leandroebner/Morse-Code-LED-Blinker repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Morse-Code-LED-Blinker design in my own project?

Yes, under the terms of its CERN-OHL-S-2.0 license, which leandroebner chose for the repository.

Can I test firmware for the Morse-Code-LED-Blinker 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.
