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.

Package included:
1 x 8 Channel 12V USB Relay Board with Case
