Should people be looking to make custom OTG solutions in the future (I don’t know, could just be me), I’ve found a couple of things that might make whatever your creations might be a bit more compact with a little bit of work.
90 Degree USB OTG up/down
OTG to USB Compact adapter
I figured that I’m definitely not going to be the last person thinking of modding the GameShell through the USB port (it is not too hard to setup, just need to find the right compact circuits), so I might as well put my findings on here.
