TOSR142 WiFi Relay kit support both Andorid and iOS and it has password. It’s a convenient and easy-to-use product that be used to control any electrical equipments. You may wish to control it with a mobile phone or a computer (etc). After configuring the WiFi module, your WiFi relay board will have a valid IP address. then Open the APP->Connect Device, Input the IP, port number and connect it, and then you can control the relays ON/OFF. The communication way also can be changed easily. Remove the WiFiBee module instead with a BluetoothBee, it becomes a Bluetooth relay.

TOSR142 is an upgraded version of TOSR04. It supports password. It can be set to latching or momentary outputs. TOSR142 allows computer control switching of external devices by using the USB port of your computer. It also has a wireless extension port, can works with Xbee or BluetoothBee or WiFibee Module, So you can control your device via zigbee or Bluetooth or WiFi!

The TOSR142 provides four volt free contact relay outputs with a current rating of up to 10Amp each. one DS18B20 temperature sensor port. The module is powered from a 5VDC power supply(or USB). The DC input jack is 2.1mm with positive core polarity, The relays are SPDT types. If you want power it with DC12V or 24V, you just need a 12V/24V-5V DC converter.


Note: Relay board default password is: 123456

Note: Please remove the WiFi module when you use USB connection.


Smartphone APP:

We also provide FREE Android/iOS App. You can control your device by your phone very easily.



Android APP(WiFi)

iPhone APP (WIFI)


Relay power rating
If the relay is used at a voltage or current exceeding this specification, the life of the contacts may be significantly shortened.

A full datasheet for the relays used on the TOSR142 is here: G5LA datasheet

If you use DC Power ,the Input voltage should be DC5V.

First Step - Install the Driver
The TOSR142 module uses FT232RL USB to UART chip . Before using the TOSR142 you will need to download the FT232RL Driver.

Connect the TOSR142 and windows will detect it and ask for the drivers. Point windows to the inf folder and it will install the driver.

The TOSR142 will now appear as a com port.

The TOSR142 operates with an easy to use command set as described in the table below.

TOSR142 Baud rate : 9600 

Test program
To get the TOSR142 up and running in the minimum amount of time we have put together an example program to demonstrate the functionality of the module.
