This transmitter is used in conjunction with the L24YK-RX4 receiver, which has the same function as the PT2262/2272 modules that are widely available on the market today. It can be used to turn on or off 6 channels of signals with just a few simple setup steps.
The 2.4Ghz RF Transmitter L24YK-TXH uses the 2.4Ghz public frequency band (no permission from the frequency regulator required), which provides a long, stable, and interference-resistant range of up to 120m. The module is developed on the basis of the 2.4Ghz SoC BK2461 IC, so it integrates superior encoding layers. In addition, the module can be linked to the receiver with just a few simple code matching steps using a button (no need to solder addresses like PT2262/2272).
The 2.4Ghz RF Transmitter L24YK-TXH can only be used with the L24YK-RX4 receiver, which is a version of the receiver with fast response because it constantly receives signals without any downtime, so it will consume more power than other versions.

Usage:
Provide 2.2~3.6VDC power to the L24YK-TXH and L24YK-RX4 modules. Then, pull down the Code Matching pin of the L24YK-RX4 receiver to GND using a button. Note that you should press and release the button immediately. Pressing it for more than 5 seconds will erase all Code Matching on the L24YK-RX4. The L24YK-RX4 can receive up to 20 Code Matching.
After pressing the button, if there is an LED connected to the B6 pin of the L24YK-RX4, you will see the LED light up continuously, indicating that it has entered Code Matching mode. This mode lasts for 10 seconds.
Pull down the Code Matching pin of the L24YK-TXH transmitter to GND using a button. If you see the LED on the B6 pin of the L24YK-RX4 blink, it is complete. The two modules can now pair and interact with each other.
When you apply VCC or GND to pins B1~B6 on the L24YK-TXH, you will see the corresponding output signal on the L24YK-RX4. If you want to latch the signal on the L24YK-RX4, connect pin B8 to Mass. In this case, 1 press will hold, and 1 press will release the corresponding signal on the signal pin.
