Multi-Control

SunFounder Multi-Control is a multi-function controller based on the Atmel ATmega32U4. With a mini USB port, it can be connected to the PC or Raspberry Pi directly. After powering, the PWR (power) LED keeps constant lighting. Press any key and the TX LED will blink, which indicates the key data has been sent. There are 6 silica gel buttons and a joystick to simulate a gamepad, a reset switch, and a mode toggle switch (for touch terminals) on the controller. Besides the buttons, there are 4 GND ports and another 10 analog touch input ports for simulating the midi devices . On the back of the board, there are 2 groups of pin headers including one group of GND, and the other corresponding to the input of the 10 keys. They are reserved for extending more control functions. There is an ICSP 6-pin header to write bootload to the chip and a mini USB port to upload the control program.
