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 to work
Extra PCB openings for better voltage isolation
Doubled high current tracks
There is no against reversed voltage! If the VCC(+12V) and GND are reversed the board will be damaged
