Feature:
1. Interference Resistance: The relay module has an optocoupler isolation component with high interference resistance. There are also Bluetooth status indicator and relay indicator.
2. Two Interfaces: The relay module retains a UART debugging interface with a baud rate of 9600 and an MCU program interface, which lays the base for your subsequent settings and operations.
3. Current Drainage Protection: This 4 channel relay can be continuously closed 100,000 times, with diode current drainage protection and short response time.
4. Remote Control: Our relay module has Bluetooth module and supports SPP protocol, the control distance can be up to 30M in open environment.
5. Practical and Safe: This relay module is made of PCB material, exquisite craftsmanship, safe and practical, no harm to users, and can be used for a long time.
