433mhz Wireless Wide Voltage Coding Transmitter + Decoding Receiver 4 Channel Output Module for 433 Mhz Remote Controls

Transmitter module Model: TX118SA-4 Transmitting power: 11dbm Emission current: 10 mA Fire speed: up to 10KB / S. Working voltage: DC 3V-24V Code: EV1527 1527 learning code Each module has a unique address code, and the address codes of K1~K4 on the same module are the same.

Receiver ModuleModel: RX480-E4Working voltage: DC3.3~5V Quiescent current: ≤5mA Output current: 10 mA Working frequency: 433MHz Receive sensitivity: -108dB Working temperature: -25~75 Working mode: instantaneous mode, self-locking (4-channel switching mode), interlock Output: The 4-channel CMOS level signal corresponds to the remote control ABCD 4 button. Pin command GND: Ground or negative + V: DC3.3~5V input D0: data output D1: data output D2: Data output D3: Data output VT: output

How to match the transmitter and receiver 1. Delete existing data: press the Learn button (on the receiver) 8 times. Response: The LED flashes 7 times. 2. Learn remote code: Press the Learn button (on the receiver) once, twice or three times (see below). The LED lights up: the learning mode is active. Press any button on the remote control. The LED flashes three times: the study is successfully completed. 3. Test: After the above operation, the receiving board can be controlled by the remote controller. Starting with step 2, more transmitters with different IDs can be additionally learned and stored. Different modes can be mixed. Button usage (set mode and start the pairing process): Press once: jog mode (instantaneous mode) Press twice: self-lock mode (4-channel switching mode) Press three times: Interlock mode (the selected channel is activated and cleared if another channel is activated)
