SKU: EB0046452
Favorites
Key Features
Android Bluetooth Wireless Control: Remotely toggle the 10A relay via a dedicated "Bluetooth Smart Control" app (Android-only) with a 10m open-range connection—simply pair with password "1234" and send hex commands (e.g., "A00101A2" to open, "A00100A1" to close) for easy on/off operation.
STM8S MCU for Stable Performance: Equipped with a high-performance STM8S microcontroller, this board ensures reliable data processing and responsive control, making it ideal for automation, home IoT, or industrial monitoring projects.
Dual Status Indicator LEDs: Features a Bluetooth connection indicator (to confirm pairing status) and a relay activation LED (to show if the relay is open/closed)—no guesswork, just clear real-time feedback.
Wide Voltage Compatibility: Handles up to DC 30V or AC 250V loads, allowing you to control devices like motors, lights, pumps, or appliances directly without additional converters (max 10A current capacity).
Compact & Developer-Friendly Design: Measuring just 20mm×62mm, it fits tight spaces, while reserved UART debugging and STM8 SWIM programming interfaces enable advanced customization—perfect for DIY tinkerers or professional developers.

Basic functions and instructions
IN+: positive terminal of the DC 12V power supply
IN-: DC 12V power source
COM: public terminal
NO: Normally open interface of the relay. The relay is suspended before closing and shorted with COM after closing
NC: normally closed interface of relay, short connected with COM before relay closing, suspended after closing
Basic operation instructions:
After the connection is correctly connected, install the "Bluetooth Smart Control" APP on the Android phone, search for the Bluetooth device and connect it. The pairing password is 1234, long press the gray box in the interface to add the serial port instruction, and input the name and content of the instruction (open the relay when the instruction content is A00101A2; Turn off the relay when the instruction content is A00100A1) and select to send in hexadecimal form, then click the corresponding box to control the switch of the relay, or download other Bluetooth apps in the APP store to control by sending instructions.
Tip: Currently, the module only supports Android system, not IOS.
