2Way Bluetooth-compatible Relay MdouleIN+, IN-: 12V power inputTX, RX: UART serial port pinsEV, GND, SWIM, NRST: STM8S microcontroller program download portLED D2 and D4 (red light): relay working indicator, light when openLED D1 (blue light): blue light status indicator, slow flashing indicates waiting to establish connection with mobile phone, steady on indicates successful connection establishment with mobile phoneTwo jumper caps are reserved: please plug to the right end during normal use (ie RX to RX1, TX to TX1). If you want to use the USB-TTL serial port module to debug the SPP-C module, please plug to the left end (otherwise Interfering)COM1, COM2: public terminalNO1: Normally open, the relay hangs before pull-in, short-circuit with COM1 after pull-inNC1: Normally closed end, the relay pull-in is short-circuited with COM1, and hangs up after pull-inNO2: Normally open, the relay hangs before pull-in, short-circuit with COM2 after pull-inNC2: Normally closed end, the relay pull-in is short-circuited with COM2, and hangs up after pull-inRelay control command (hexadecimal HEX form): turn on the first-way relay: A0 01 01 A2Close the second relay: A0 01 00 A1Turn on the second relay: A0 02 01 A3Close the second relay: A0 02 00 A2
4 Way Bluetooth-compatible Relay MdouleIN+, IN-: 12V power input;TX, RX: ART serial port pins;5V, GND, SWIM, NRST: MCU program download port.LED D2/D3/D4/D5 (red light): relay work indicator light, light when openLED D1 (blue light): Bluetooth-compatible status indicator, described as follows:When flashing slowly, it means waiting to establish a connection with the phone;When it is always on, it means a successful connection with the mobile phone.Two reserved jumper caps: please plug them to the right end during normal use (i.e. RX connected to RX1, TX connected to TX1)If you want to use the USB to TTL serial port module to debug the SPP-C module alone, please plug it to the left end (otherwise there may be interference).COM1: public terminal;NC1: normally closed end, the relay is short-circuited with COM1 before pull-in, and hangs up after pull-in;NO1: Normally open, the relay is suspended before pull-in, and shorted to COM1 after pull-in. COM2: public terminal;NC2: normally closed end, the relay is short-circuited with COM2 before pull-in, and hangs up after pull-in;NO2: Normally open, the relay hangs open before pull-in, and short-circuit with COM2 after pull-in. COM3: public terminal;NC3: normally closed end, the relay is short-circuited with COM3 before pull-in, and hangs up after pull-in;NO3: Normally open, the relay is suspended before pull-in, and shorted to COM3 after pull-in. COM4: public terminal;NC4: Normally closed end, the relay is short-circuited with COM4 before pull-in, and hangs up after pull-in;NO4; normally open, the relay hangs before pull-in, short-circuit with COM4 after pull-in.2 Relay control instructions (16 hex system),Turn on the first relay: A0 01 01 A2Close the first relay: A0 01 00 A1Turn on the second relay: A0 02 01 A3Close the first relay: A0 02 00 A2Turn on the third relay: A0 03 01 A4Close the third relay: A0 03 00 A3Turn on the fourth relay: A0 04 01 A5Close the fourth relay: A0 04 00 A4
