TinySine 2 Channel Smartphone Bluetooth Relay Kit for Android and iOS – TOSR02

TOSR02 V2 Bluetooth Relay kit supports both Android and iOS. It’s a convenient and easy-to-use product that can control any electrical equipment. You may wish to pair it with a mobile phone or a computer (etc.). Open the APP > Connect Device, use your phone to search for a new Bluetooth device. The module will appear as “BT Bee-BLE” (iOS) or “BT Bee-EDR” (Android). Connect it, and then you can control the relay’s ON/OFF. The communication way also can be changed easily. Remove the Bluetooth Bee module instead with a WiFiBee, and it becomes a WIFI relay.

The TOSR02 provides two-volt free contact relay outputs with a current rating of up to 10Amp each. 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 type. So if you want to power it with DC12V, you need a 12V/24V-5V DC converter.
