Post by NoahWL1 on imgur – using the Adafruit Trinket M0 to talk to a Nintendo Switch as a “modchip”. Now ignorant editor me will say “I don’t know about such mods but at least in the US they just ruled that we have the right to repair our gear” so I’d guess this is a repair. As with any repairs not put out by Adafruit, you’re on your own on this. Now Noah writes:
This is the guide I got a lot of info from here. I had this planned out before I stumbled upon this, but it was a huge help to have a list of probe points to tap into on the Switch motherboard. This thread is awesome and a great help if you decide to this yourself and run into issues. “Nintendo Switch modchip install cause I’m bored and have nothing else to do.”
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
