$39.95

TOSR121 Bluetooth Relay kit supports Android and iOS, and it has a password. 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, and 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 way we communicate can also be changed easily. Remove the Bluetooth Bee module instead with a WiFiBee, and it becomes a WIFI relay.

TOSR121 is an upgraded version of TOSR02. It supports passwords. It can be set to latching or momentary outputs. TOSR121 allows computers to control external device switching by using your computer’s USB port. It also has a wireless extension port that can work with Xbee BluetoothBee or WiFibee Module so that you can control your device via ZigBee Bluetooth or WiFi!

The TOSR121 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 by 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 or 24V, you need a 12V/24V-5V DC converter.

  • Note: The relay board’s default password is: 123456
  • Note: Please remove the Bluetooth module when you use the USB control.

Smartphone APP:

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

  • Android APP (Bluetooth)
  • iPhone APP (Bluetooth)

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 TOSR121 is here: G5LA.
  • If you use DC Power, the Input voltage should be DC5V.

First Step – Install the Driver

  • The TOSR121 module uses FT232RL USB to UART chip. Therefore, before using the TOSR121, you must download the FT232RL Driver.
  • Connect the TOSR121, and Windows will detect it and ask for the drivers. Point windows to the inf folder, and it will install the Driver.
  • The TOSR121 will now appear as a com port.

Shipping Policy

FAST DELIVERY! We ship worldwide via FedEx, UPS, DHL, and USPS because they’re Fast, Reliable, Affordable, and Easily Trackable. We process orders in 24 hours; delivery may take 4 to 7 days or sooner, depending on your location. Once shipped, you will receive an email with your tracking number.

Ships From: Not all our products are shipped from the USA; we ship some from regions like China, Taiwan, or Europe. Therefore, the tariff you will pay will differ depending on which country your order will be shipped from because not all countries charge the same amount. For example, if the US imposes a 30% tariff on goods from China, other countries may impose a much lower tariff. Check the "Ships From:" label on this product page to see from which country we will ship it.

TARIFF: While not all products require a tariff, some may require a minimal or no tariff. If applicable, the buyer will pay the tariff within their respective country. The total amount of your order does not include a tariff. Please enter a reachable phone number during checkout so the Shipping Company can contact you to pay the tariff once your parcel arrives at your destination.

Why don't we add tariffs to the product's retail price? If all countries imposed the same tariff amount and used the same currency, we would have added the tariff amount to the product price. However, we do not do that because each country charges a different amount and uses a different currency, while some do not even charge a tariff. Therefore, we can't add a tariff to the product's retail pricing. Oz Robotics' manufacturing partners, or suppliers are not responsible for tariffs. We will not cancel your order or refund you if you do not pay the tariff. More Details.

SHIPPING COSTS: For some industrial products, e.g., heavy wheels, CNC machines, etc., the shipping cost is calculated based on the product weight, not quantity. For lower shipping costs for orders with multiple items, please email us at sales@ozrobotics.com before you buy. We show shipping rates on the product page under the SHIPPING tab. To see the shipping cost for your country, click add to cart on the product page.

PRODUCT DATASHEET AND MANUAL: If applicable, the Product Documentation, such as the Datasheet, CAD Design, STP Files, Manuals, Reference Materials, and Tutorials, will be available for download upon purchase from the My Account as needed.
