I'm starting to think about an expansion module for Gamebuino... which extra features you would like to have?
Edit: which list:
- L/R buttons
- Wireless (radio)
- RGB LEDs on the edge of the acrylic case to change the whole Gamebuino color (as the PCB is white). It could pulse red when you're about to die for example.
- Vibration motor
- 16 extra GPIO using an I2C extander (but some of them will be used to be the CS pin of SPI devices)
- 32kB of extra RAM, but it won't be directly addressable
- Extra screen, something like a 128x32px oled screen, so it will fit above the current screen without making a (fragile) excrescence. Could be used to display stats, text or a minimap.
- 3 axis accelerometer
- analog Joystick
