1. It's designed with MICRO USB and serial port for communicating with outside. It's more convenient to connect module with PC and other device.
2. The normal working voltage of this module is 5V and it has the 5V power port.













channel count of module






working current






input voltage



whether have serial port






baud rate of serial port






module control frequency





whether have power interface


Modules are with Micro USB, serial port and TTL serial interface.

  • Micro USB: Standard micro USB female adapter.( can use the USB extension cord to connect with the PC and the other devices)
  • TX: Transmit
  • RX : Receive
  • 5V:Volt current condenser
  • GND : Ground
  • 5V power socket: Only the ICSE014A module has this interface.( it works when the MICRO USB can not supply enough power)

How to use it?

1).USB Usage method

    These modules use the USB port to connect with the PC as following:

Open the "Relay Board Manager" to control the module directly. Please refer the usage of this software to "Relay Board Manager_Reference".

2)Serial port using method

These modules can use the serial port to connect with other communication devices. These modules can receive the Single-byte instruction from the upper monitor.
Upper Monitor    0x50     0x51
ICSE014A          0xAC

These modules will work normally after they receive the "0X51" instruction. The bytes which these modules receive can control the modules directly and every singly byte control one channel of the module( "0" means start, "1"means stop).

The details are as following:







Control the relay K1


Control the relay K2


Control the relay K3


Control the relay K4


Control the relay K5


Control the relay K6


Control the relay K7


Control the relay K8

I had a little trouble with the protocol documentation, but once I figured that you're supposed to send 0x50 at startup to get the module's attention, and then send 0x51 followed by a byte containing the desired states of the relays as bits of that byte all went well. One other issue I run into is that I have to power the relay from the header pin instead of the power jack. There appears to be a big voltage drop on the power jack. All in all, it is definitely worth the price I paid for it. https://www.youtube.com/watch?v=yasznSglN2s
