Module description
1. The onboard square USB interface, stable connection
2. Use imported high-performance USB control chip
3. Using a special relay to drive the chip ULN2803, the relay works more stable
4. Use genuine relay
5. Military-grade PCB board production
6. Board power socket and terminal, two ways to access the power supply are convenient and flexible. When the power is connected, the relay can remain set even if the computer is turned off or the USB is removed from the computer.
7. Fixed hole size:3mm
Note:Due to the characteristics of the USB protocol, this module is not suitable for use in places with large electromagnetic interference! If you want to use it, please do electromagnetic shielding and buy a good USB data cable with electromagnetic shielding.
