This is an USB enabled relay module that allows you to use the computer for controlling the relay output. This module is ideal for home automation, robotics, and more.

Specifications

  • On-board high-performance microcontroller chip
  • On-board CH340 USB to UART converter chip
  • On-board LEDs for power indication and relay status indication
  • Output capability 10 A / 250 VAC, 10 A / 30 VDC
  • PCB Size: 43.6 x 16.4 mm

The board uses a baud rate of 9600 bps (8 data bits, 1 stop bit, no parity) for the virtual serial port and the following communication protocol:

  • A start byte: 0xA0
  • A byte to indicate the relay address: 0x01
  • A byte to indicate the state of the relay: 0x00 (off) or 0x01 (on)
  • A check code (0xA2 for on or 0xA1 for off)

Communication example:

  • A0 01 01 A2  (the hexadecimal values of the bytes for turning the relay on)
  • A0 01 00 A1  (the hexadecimal values of the bytes for turning the relay off)
