This project is a continuation of the Ultrawide DS: https://www.pcbway.com/project/shareproject/A_DIY_Steam_Deck_Ultrawide_DS_329ab300.html

This time I wanted to build a magnetic clip on graphics card to the handheld gaming device. The goal was to cram in a desktop graphics card which I could in theory adapt to an m.2 pcie SSD enclosure and plug into my laptop with Thunderbolt 3. Though in practice the GPU functionality was very inconsistent and would rarely work. But in the end I'd say it looks cool. The add-on has slide on battery modules to power the graphics card with usb-c. The RX6400 is mounted inside, with a Heatsink CNC machined by PCBWay, and enclosed in a Nylon printed shell so it can withstand the heat.

Here is the full video documenting the process: https://youtu.be/TwQN94SaY_c?si=nTiSUVFpNsc9jpi_

Once again this project was made with the intent of entertainment, and showing the capabilities of PCBWay, thus the models are not good enough for public release.
