Package : moduleis_customized : YesModel Number : L24YK-RX4 L24YK-TXHOperating Temperature : normalDissipation Power : lowSupply Voltage : 2.8-3.6VApplication : ComputerCondition : NewType : Voltage RegulatorBrand Name : EC Buying : Mainland ChinaSmart Electronics Experiment : Switch And Sensor For Arduino STM32antenna : PCB antennaSight distance : 100 m 100mThe 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 metersCharacteristic:No development required2.8-3.6V power supplyThe standby current at the transmitting end is 10uAWorking frequency: 2.4-2.5GHzSize 23.3 * 13.7 * 2.1mmWith LED indicator lightsOn board antenna with external antenna interfaceNotes:1. A maximum of 20 transmit es can be matched with a single receiver. If there are more than 20, the first e 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 on is pulled down or grounded, the on 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 level4. 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),
