Features:

1: Widely used

2: Control distance: 10M (open environment)

3: Provide Bluetooth relay control APP

4: Stable performance

5: Easy to use

Descriptions:

Single Bluetooth relay module includes 1 5V/10A or 1 12V/10A relay module and SPP-C Bluetooth serial port slave module, which can control the switch of the relay by sending instructions through the mobile phone APP. The new model is more practical and has better performance. Stable.

1. Onboard high-performance MCU and SPP-C Bluetooth 2.1 slave module;

2. Provide Bluetooth relay control APP;

3. Control distance: 10M (open environment);

4. Working voltage: DC12V;

5. Onboard 1 way 12V, 10A/250V AC 10A/30V DC relay, which can be activated continuously for 100,000 times, has diode effusion protection, and has a short response time;

6. Onboard Bluetooth status indicator and relay indicator;

7. Reserve the UART debugging interface, which can be used to modify the Bluetooth pairing password.

8. Board size: 62*20mm

1. Connect the power supply: the IN+ and IN- of the module are respectively connected to the positive and negative poles of the 5V/12V (subject to the actual purchase) of the power supply.

2. Use APP to control 1 relay. There are 2 APPs to choose from: one is a dedicated APP for Bluetooth relay developed by LC Electronics, and the other is a general APP downloaded from the Android App Store

2.1. Instructions for using Bluetooth relay dedicated APP:

2.1.1. Install the "LCBS Test Program" APP, Bluetooth serial port transmission tool on the Android mobile phone, open the APP and click "Search Bluetooth", the default Bluetooth name is generally BTA-04, JDY-30, SPP-C, etc., connect to the mobile phone For the Bluetooth module, enter the password and click to confirm (the initial password is 1234). After the connection is successful, the blue light changes from slow flashing to constant light, and then click the square to control the relay switch.
