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 5 VDC or order to work.
• There is no protection against reversed voltage! If the VCC(+5V) and GND are reversed the board will be damaged!
• The board can not work without computer
