About the Mora blinker PCB

Mora blinker is an open source AVR/Arduino PCB design by kissadamfkut, published on GitHub under the MIT license. It is a 2-layer board measuring 33 × 30 mm, with 15 components from 7 distinct parts.

Its main chip is the ATtiny13A-SS, from the AVR/Arduino family. By type, the board carries 6 resistors, 5 diodes, 1 IC, 1 battery holder, 1 switch and 1 capacitor.

From the project

Simple LED blinker with ATtiny13A for educational purposes

- Provide a simple and cheap educational embedded project - Demonstrate basic electric design - Demonstrate both C++ basics and advanced tricks - More entertaining first program than a 'Hello world' - Educate for software design in low-end environments

- The schematics and the PCB board can be found in the hw folder. You can open the files with KiCAD 6 - The software is in the sw folder. Do not forget to also pull the git submodules! - The build environment for the software includes avr-gcc 11.2, avrdude 6.4 and make 4.3 - Do not connect the battery when using a 5V ISP! - After building the…

Mora blinker: common questions

What microcontroller does the Mora blinker use?

The Mora blinker is built around the ATtiny13A-SS, from the AVR/Arduino family.

How big is the Mora blinker PCB?

The Mora blinker measures 33 × 30 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Mora blinker?

15 components, from 7 distinct parts. The full bill of materials is listed on this page.

Where can I download the Mora blinker design files?

From the kissadamfkut/mora_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 Mora blinker design in my own project?

Yes, under the terms of its MIT license, which kissadamfkut chose for the repository.

Can I test firmware for the Mora 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.
