About the Medalv2 PCB

Medalv2 is an open source AVR/Arduino PCB design by VincentPeters, published on GitHub under the MIT license. It is a 2-layer board measuring 45 × 45 mm, with 22 components from 8 distinct parts.

Its main chip is the C145558, from the AVR/Arduino family. By type, the board carries 8 diodes, 8 resistors, 2 capacitors, 1 IC, 1 connector and 1 battery holder.

It belongs with the audio designs in this gallery.

From the project

PCB ping-pong medal: round ATtiny1616 board with an 8-LED ring animation, designed code-first (circuit-synth + headless pcbnew/Freerouting). The board is the medal.

Experiment: generate the medal's KiCad schematic + netlist from Python, with no GUI, using circuit-synth. This is the "AI can drive the hardware phases" proof-of-concept.

This generates medal/ (.kicadpro, .kicadsch, .net, .json).

The auto-drawn KiCad sheet is label-based and scattered (see the ERC note above). For documentation, drawschematic.py redraws the same circuit with real wires + standard VCC/GND power flags — ATtiny1616, the 8 resistor+LED chains, CR2032/slide-switch power, decoupling, and the UPDI pads. It is verified net-for-net against medal/kdgpingpongmedal.net. Outputs…

Medalv2: common questions

What microcontroller does the Medalv2 use?

The Medalv2 is built around the C145558, from the AVR/Arduino family.

How big is the Medalv2 PCB?

The Medalv2 measures 45 × 45 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Medalv2?

22 components, from 8 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 Medalv2 design files?

From the VincentPeters/pingpong-medal repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Medalv2 design in my own project?

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

Can I test firmware for the Medalv2 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.
