About the C2c-64 PCB

C2c-64 is an open source AVR/Arduino PCB design by jsanpe, published on GitHub under the MIT license. It is a 4-layer board measuring 50 × 50 mm, with 106 components from 51 distinct parts.

Its main chip is the ATmega328PB-MU, from the AVR/Arduino family. Other key parts include the ADV7393-Video, ADV7180-32LFCSP, TLV70018_SOT23-5, AMS1117-3.3 and 3xRCA_CONN. By type, the board carries 39 capacitors, 32 resistors, 8 ICs, 7 diodes, 6 inductors and 5 connectors.

It belongs with the retro computing designs in this gallery.

From the project

A Composite & S-video to Component transcoder for the OSSC

Designed with the C-64 in mind, it also supports composite and s-video signals from other systems, including the N64. A compatibility chart will soon be available in the wiki section of this project.

This is an open hardware implementation of a board to convert Composite and S-Video signals into Component video. The component output from C2C-64 can be directly connected to an OSSC, effectively adding compatibility with Composite and S-Video input to this great scaler.

The KiCad project lives in the jsanpe/c2c-64 repository on GitHub; these links point at the commit this page was built from.

C2c-64: common questions

What microcontroller does the C2c-64 use?

The C2c-64 is built around the ATmega328PB-MU, from the AVR/Arduino family.

How big is the C2c-64 PCB?

The C2c-64 measures 50 × 50 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the C2c-64?

106 components, from 51 distinct parts. The full bill of materials is listed on this page.

Where can I download the C2c-64 design files?

From the jsanpe/c2c-64 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the C2c-64 design in my own project?

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

Can I test firmware for the C2c-64 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.
