About the Stecchino PCB

Stecchino is an open source AVR/Arduino PCB design by pepelepoisson, published on GitHub under the MIT license. It is a 2-layer board measuring 97.2 × 31.8 mm, with 9 components from 8 distinct parts.

Its main chip is the ARDUPROMINI_pins_on_4_sides, from the AVR/Arduino family. By type, the board carries 2 connectors, 2 switches, 1 test point and 1 resistor.

It belongs with the power & battery and sensors designs in this gallery.

From the project

Stecchino is an home-made game where you need to balance a stick-like device at the tip of your fingers. The longer you can keep it balanced the more LEDs are lit on the Stecchino device. Can you do better than your friends?

Total: Approx 25.5CAD for electronics + cost of woodwork.

Make one yourself and let me know! A few measurements to establish minimum VCC before Stecchino starts to bug.

Stecchino: common questions

What microcontroller does the Stecchino use?

The Stecchino is built around the ARDUPROMINI_pins_on_4_sides, from the AVR/Arduino family.

How big is the Stecchino PCB?

The Stecchino measures 97.2 × 31.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Stecchino?

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

Where can I download the Stecchino design files?

From the pepelepoisson/Stecchino repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Stecchino design in my own project?

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

Can I test firmware for the Stecchino 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.
