Notice:
- When the board is connected to the PC and the PC is restarted, the relays will be toggled several times. This is because of the structure of the FTDI chip.
- The device must be supplied with 12 VDC or order to work.
- There is no protection against reversed voltage! If the VCC(+12V) and GND are reversed the board will be damaged!
- The board can not work without computer
