About the UnoCart 2600 PCB

UnoCart 2600 is an open source STM32 PCB design by f1ac0, published on GitHub. It is a 2-layer board measuring 41.3 × 45.7 mm, with 22 components from 12 distinct parts.

Its main chip is the STM32F407VGTx, from the STM32 family. Other key parts include the SPX3819M5-L-3-3 and XC6206PxxxMR. By type, the board carries 12 capacitors, 3 ICs, 3 connectors, 2 jumpers and 2 resistors.

Atari 2600 replacement parts and expansions

While waiting for the system to dry after a complete clean and rust removal I found the useful projects below to help me start with this system I didn't know anything about. - First I needed some game so I put together a ROM cartridge on a breadboard and created a PCB from it. - Then not a single TV receiver I had could tune the video and audio signals correctly, but a BT848 PCTV PCI card. The mod by Eddy Foucault worked perfectly, I made my own version with CMS components and 5v only. - At last I removed the regulator to power the console from a modern 5V power source.

UnoCart 2600: common questions

What microcontroller does the UnoCart 2600 use?

The UnoCart 2600 is built around the STM32F407VGTx, from the STM32 family.

How big is the UnoCart 2600 PCB?

The UnoCart 2600 measures 41.3 × 45.7 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the UnoCart 2600?

22 components, from 12 distinct parts. The full bill of materials is listed on this page.

Where can I download the UnoCart 2600 design files?

From the f1ac0/Atari2600 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the UnoCart 2600 design in my own project?

The repository has no license, so all rights stay with f1ac0. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the UnoCart 2600 without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
