The module operates in the 2.4G frequency band, with built-in MCU and wireless transceiver chip, characterized by no development, low power consumption, and convenient use. L24YK is divided into a transmitting module and a receiving module, which directly outputs 6 switch signals and has a learning pairing function. One transmitting module can pair with multiple receiving modules, and the receiving end can also set flipping and jogging modes, with a maximum line of sight of up to 100 meters

Characteristic:

No development required

2.8-3.6V power supply

The standby current at the transmitting end is 10uA

Working frequency: 2.4-2.5GHz

Size 23.3 * 13.7 * 2.1mm

With LED indicator lights

On board antenna with external antenna interface

Notes:

1. A maximum of 20 transmit codes can be matched with a single receiver. If there are more than 20, the first code value will be overwritten. One receiver can be controlled by up to 20 transmitters.

2. A transmission can be matched by countless receivers, that is, one transmission can control countless receivers.

3. In the article, the button is pulled down or grounded, the button is released and pulled up to connect to VCC, the light is on to output a high level, and the light is off to output a low level

4. When the module is attached to the user’s PCB board, the module antenna cannot be covered with copper or wired, otherwise it will affect the distance.

5. The module adopts a PCB antenna with reserved external antenna holes (to enable, the 0 ohm resistor connecting the PCB antenna needs to be removed),
