j0y+ m0dul is a game controller for your r0ket .
Just connect the j0y+ m0dule to your r0ket. Eventually you will have to flash a new firmware onto the r0ket, we are not sure about this at the moment.
This is a gamepad, so feel free to program games that use a analog stick, 4 buttons, some LEDs and perhaps a vibro motor (yes, we live in fear of Immersion). And good god, make them multiplayer!
When you mount the j0y+ m0dul make sure the LEDs are as near to the display as possible. If you keep that in mind you can't mount the module wrong.
(sorry for that, but I have the feeling this might be necessary)
Step by step assembly instructions, schematic, board, eagle, bom, etc coming soon…
You will have to put a new firmware into your r0ket, but we have no idea how to do that at the moment. Stay tuned!
