Project I've been working on that I'm very passionate about. A fully upgradeable gaming handheld where you can upgrade the battery, mainboard (cpu), ram, storage by utilising Frameworks modular components. I will be selling it soon as a DIY kit for those that want another way to reuse (or buy new) their Framework components.
Can be currently upgraded to a Ryzen 7840U mainboard and a 61Wh battery for maximum performance.
Components used in video:
Intel 1260p mainboard
16GB ram
512gb ssd
55Wh Battery
dual speakers
7 inch FHD touchscreen
High speed WIFI & Bluetooth
Yes, they are. This is just a PC in a handheld form factor. I would say that Steam Deck isn’t modular since the only pieces that can realistically be upgraded are the SSD and analog sticks. But this allows motherboard, screen, RAM, and controllers.
