Description
Overview:5V Bluetooth 4-channel relay module equip with SPP-C Bluetooth 2.1 slave module and 8 bit high performance MCU, you can control the relay with cellphone APP directly.
Specification:
1. On-board N76E003/STM8S003 and SPP-C Bluetooth 2.1 module2. The relay can be controlled with APP3. Effective control distance(on open area): 10m4. Power supply: 5V5. On-board 5V, 10 A / 250 v AC 10 A / 30 v DC relay, absorb 100000 timescontinuously, Module with diode effusion protection, short response time6. On-board optocoupler isolation components, anti-interference ability is strongly7. On-board Bluetooth indicator and relay indicator LED8. On-board preserved UART debug interface(Baud rate is 9600) and MCU program interface9. Size: 62.7 x 60mm10. Weight: 56g
Interface:
IN+, IN-: 5V power inputTX, RX: UART communicationSWIM, NRST: MCU program interfaceLED D2/D3/D4/D5(red): Relay indicatorLED D1(blue): Bluetooth state indicator, the description of D1 as below:(1) It's means wait for establishing connection with the APP when D1 blink slowly.(2) It's means the Bluetooth connect with the APP successfully when D1 on all the time.
Package included:
1 x Relay module
