- board USB interface, the connection is stable
- using imported high performance USB control chip
- using the special relay driver chip ULN2803, the relay work more stable
- using the genuine pine music relay
- military grade PCB board production
6 board power supply sockets and terminals, two ways to access the power supply convenient and flexible. After connecting the power supply, even if the computer is shut down or the USB is pulled out from the computer, the relay can also keep the setting state.
