1. Interface on Board
(1) External power supply port: connect DC5V power. Due to the limited USB output current, it is recommended to use external power supply when more than 2 relays are using;
(2) USB power supply / external power supply switching: “Usb_P” for USB power supply, “Ext_P” for external power supply;
(3) USB socket: USB connect / power supply;
(4) Reserved USB interface.
