I'm thinking of fabricating a circuit board for DIY controller enthousiasts, to share what i've learned along the way.
- single pcb based on atmega32u4
- additional 4 channel 14-bit analog inputs, plus 4 for each connected slave board (throttle, rudder) (arduino only has 10-bit ADC)
- plug and play USB HID controller soni works on Windows, OSX, XBox, PS4, etc.
- 16 digital inputs, plus 16 per each connected slave board
- NeoPixel led driver on each board to allow full RGB led feedback.
- expandable with I2C slaves
- the firmware will be based on Arduino with full open source support
- SMT technology
- fully solderered and assembled with connectors, headers or screw terminals.
the selling point over a standard arduino will be that all pchips are connected, all ports are broken out ready for connecting switches, so no breadboard contructions.
would people be interested in such a board?
