Please Note:If you need the transmitter to work with your own receiver, you must make sure 100% that your receiver is 433mhz Frequency, does your receiver have a learning button to learn the transmitter code? And does your receiver can be compatible with 1527 ic chip transmitter. Whether the receiver and transmitter can work together or not, their frequency, IC chip and shock resistance must be taken in to consideration.Features:*Super small body, and it occupies less space. The receiver board size is only about 3.5*1.5*0.8cm. Customizable special code: MCU type. *Very convenient to use, simple wiring diagram connection way. Three working modes: momentary, toggle, latching three modes.*Wireless control LED lamp string, Christmas tree light string, light control switch, router, shop light box signboard, glowing signboard, monitoring equipment, servers, alarm devices, etc.*Optional fixed encoding type: PT2262 / EV1527 / HT6P20B Learning code. Support remote control up to 20 pieces.*Learning pair code: it can work with any remote control with the same frequency, so you needn't worry about losing remote control any more. (If the remote control is lost, buy one and pair with the PCB board is OK.)Application environment:Remote control switch, motorcycles, automobile anti-theft products, home security products, electric doors, shutter doors, windows, remote control socket, remote control LED, remote audio remote control electric doors, garage door remote control, remote control retractable doors, remote volume gate, pan doors, remote control door opener, door closing device control system, remote control curtains, alarm host, remote control motorcycle, remote control electric cars, remote control MP3.Specifications:Mini Relay Switch:Working voltage: DC 3.7V~12VMaximum load: 2AStatic current: 3.6mA ~ 5.5mAWorking frequency: 433MHzRF working mode: superheterodyne receptionReception sensitivity: -107dBmSupport coding format 1527 learning codeInput: DC 3.7V~12VOutput: DC 3.7V~12VModulation mode: ASK (superheterodyne)Working mode: Momentary, Toggle, Latching ModeNumber of stored remote controls: 20Learning style: Learning ButtonWorking temperature: -20 degrees 80 degrees.Board size: 35mm * 15mm * 8mm (length * width * high)Remote Control:Operating frequency: 433.92MHzPower by: 12V 27A (included )Material: PVCButton: 2 buttonSize(Each): 60mm * 32mm * 16mmOperating voltage: 3V Operating Current: 12mATransmitting power: 10mwModulation mode: ASK (AM)Encoding type: LearningTransfers distance: 80mPairing & Delay:Jog code pairing: After turning on the power, press the learning button once to let go, the LED flashes once to enter the learning state, press the remote control A button, the LED flashes off and the learning is successful.Self-locking Code Pairing: After turning on the power, press the learning button 2 times to release your hand, and the LED flashes 2 times to enter the learning state. Press the remote control A button, and the LED flashes off to learn successfully.Interlocking Code: Press the learning button 3 times after the power is turned on, the LED flashes 3 times to enter the learning state, press the remote control A key, the LED flashes 3 times immediately, then press the remote control B key, the LED flashes off and learns success.Delay for Five Seconds: Press the code button on the control board 4 times in a row, the LED indicator flashes 4 times. After the LED indicator lights up, press the remote control button that needs to be coded. The LED indicator on the control board blinks 3 times in a row. The code was successful.Delay for Ten Seconds: Press the code button on the control board 5 times in succession, and the LED indicator flashes 5 times. After the LED indicator lights up, press the remote control button that needs to be coded. The LED indicator on the control board blinks 3 times. Code success.Fifteen Seconds: Press the code button on the control board 6 times in succession, and the LED indicator flashes 6 times. After the LED indicator lights up, press the remote control button that needs to be coded. The LED indicator on the control board blinks 3 times. Cod
