About the Atari link PCB

Atari link is an open source RP2040/RP2350 PCB design by hildenborg, published on GitHub under the MIT license. It is a 2-layer board measuring 58 × 62 mm, with 24 components from 11 distinct parts.

Its main chip is the Pico, from the RP2040/RP2350 family. Other key parts include the MAX3232, SN74LVC245 and 74LVC244. By type, the board carries 10 resistors, 7 capacitors, 4 ICs and 3 connectors.

Atari link: common questions

What microcontroller does the Atari link use?

The Atari link is built around the Pico, from the RP2040/RP2350 family.

How big is the Atari link PCB?

The Atari link measures 58 × 62 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Atari link?

24 components, from 11 distinct parts. The full bill of materials is listed on this page.

Where can I download the Atari link design files?

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

Can I use the Atari link design in my own project?

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

Can I test firmware for the Atari link without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
