5V 1 Channel Bluetooth Relay Module

The single channel Bluetooth relay module contains a 1 channel 5V / 10A relay module and spp-c Bluetooth serial port slave module. The gate sends instructions to switch the relay through the mobile phone app. It is a new and modified version, more practical and more stable performance.

Feature description
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. An on-board 12V, 10A / 250V, AC10A / 30V DC relay, which can be pulled for 100000 times continuously, with diode leakage protection and short response time;
6. Onboard Bluetooth status indicator and relay indicator;
7. UART debugging interface is reserved, which can be used to modify Bluetooth pairing password, etc.
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 5V
2. APP to control 1-way relay. Two apps are available: one is a special app for Bluetooth relay developed by elsai electronics, and the other is a general app downloaded from Android application mall.
2.1. Instructions for using special app for Bluetooth relay:
2.1.1 Install the "lcbs test program" app and Bluetooth serial port transmission tool on the Android mobile terminal. Open the app and click on "search". The default Bluetooth names are generally bta-o4, jdy-30, spp-c, etc. Connect the mobile phone to the Bluetooth module, enter the password and click OK (the initial password is 1234). After the connection is successful, the blue light changes from slowly flashing to steady on, and then click the box to switch off the relay.
