What if the modular computing evangelists at Framework decided to make a handheld? YouTuber Pitstoptech has largely answered this question by building a “fully upgradeable gaming handheld” around one of Framework’s upgradable motherboards.
Pitstoptech intends to prepare and sell handheld DIY kits “soon,” based on the prototype design you see in the pictures / video.
Framework is also releasing their GPU modules. Hopefully someone finds a way to make that work with a handheld as well, although the form factor of the module might not be handheld-friendly.
