8-Channel Micro USB Relay Module USB Smart Control Switch USB Intelligent Control Switch
- NOYITO 8-Channel Micro USB Relay Module is equipped with a stable USB to serial port chip and a microcontroller. It can use the serial port debugging software to send serial commands on the computer to control the opening and closing of the 4-channel relay.; Onboard high performance microcontroller chip, CH340 USB control chip. Relay ON/OFF status query command: 0xFF.; IMPORTANT TIPSPower supply voltage: DC5V. Support USB power supply/external power supply switching. (External power supply interface: connect to the power supply 5V, because the output current of the USB port is limited, it is recommended to use an external power supply when using more than 2 relays); On-board 5V relay, 10A/250VAC, 10A/30VDC relay, long relay life, can work 100,000 times continuously.; Module with overcurrent protection and relay diode freewheel protection.With power LED indicator and relay status LED.

Hardware introduction and description
Board size: 76.9 x 80.6 mm Board
Interface Description:
COM1: common;
NC1: normally closed;
NO1: normally open..........
COM8: common;
NC8: normally closed;
NO8: normally open.
Communication protocol description: Default
communication baud rate: 9600BPS Turn on the 1-channel relay switch: A0 01 01 A2 Turn off the 1-channel relay switch: A0 01 00 A1 Turn on the 2-channel relay switch: A0 02 01 A3 Turn off the 2-channel relay switch: A0 02 00 A2 Turn on the 3-channel relay switch: A0 03 01 A4 Turn off the 3-channel relay switch: A0 03 00 A3...... Turn on the 8-channel relay switch: A0 08 01 A9 Turn off the 8-channel relay switch: A0 08 00 A8 Relay ON/OFF status query command: 0xFF USB switch communication protocol Data (1) --- start flag (default is 0xA0) Data (2) --- switch address codes (0x01 and 0x02 represent the first and second switches, respectively) Data (3) --- operating data (0x00 is "off", 0x01 is "on") Data (4) --- check code
Usage Description:
1. Connect the USB relay module to the computer and install the CH340 USB to serial chip driver
2. Open the STC-ISP, SSCOM32 such serial debugging software, select the baud rate of 9600, in hexadecimal (hex) form send A0 01 01 A2 and A0 02 01 A3 can be opened the first and second relay; Send in hexadecimal (hex) A0 01 00 A1 and A0 02 00 A2 can be turned off the first and second relay, respectively.
Relay status obtain: Send FF in hexadecimal (HEX) to query. For example, if the 1st, 2nd, 3rd, and 4th relays are open, and the 5th, 6th, 7th, and 8th relays are closed, inputting FF (HEX) to obtain the relay status will return the following data: 01 01 01 01 00 00 00 00. 01 means the relay is open. 00 means the relay is closed.
