IoT Smart Home Android Phone APP Controlled Light Switch Wireless Remote Relay Switch 2 Channel dc 5v Relay Module
The 5V dual-channel Ble relay module includes two 5V/10A relay modules and a SPP-C Ble serial slave module, which can be used to control the relay switch by sending commands through the mobile phone APP.

On-board 2-way 5V, 10/250VAC10A/30VDC relay for continuous suction of 100,000 times, with diode effluent protection and short response time
Onboard Ble status indicator and relay indicator
Reserved UART debug interface and STM8 SWIM program download interface
| Working voltage | DC5V |
| Board size | 40*64.5mm |
IN+, IN-: 5V power input
5M, GND, STMSS, SWIM, NRST: STM8S microcontroller program download port
LED D1 (blue light)
The Ble status indicator is described as follows:
(1) Slow learning means waiting to establish a connection with the mobile phone;
(2) When it is always on, it means that the connection is established successfully with the mobile phone.
COM1: Public
NO1: Normally open, the relay is suspended before being sucked, and shorted after COM1
NC1: Normally closed end, shorted to COM1 before the relay is pulled in, and suspended after suction
Relay control instruction, hexadecimal HEX form
Open the first relay: A00101A2
Turn off the first relay: A00100A1
Open the second relay: A00201A3
Turn off the second relay: A00200A2
TX, RX: UART serial port pin
LED D2 and D4 (red light): relay work indicator, lit when turned on
2 wire caps reserved: Please plug in the right end during normal use (ie RX connected to RX1, TX to TX1). If you want to use the UsB to TTL serial module to debug the SPP-C module separately, please insert it to the left end (otherwise There will be interference)
COM2: public side
NO2: Normally open, the relay is suspended before being sucked in. After the suction, it is short-circuited with COM2.
NC2: Normally closed end, short-circuit with COM2 before the relay is pulled in.
