MhomeElectronic PK-305 Module PCB

Product Information

The PK-305 Module is a communication module that operates on a frequency of 433.92MHz ISM RF. The module contains the necessary circuitry for wireless communication. The module is equipped with a PCB antenna, connected through an F-type connector on the PCBA. The module requires a 3V power supply.

The module features three sets of buttons and LED indicators. Each set consists of an ON button, an OFF button, and a LED diode. The LED diode indicates the status of signal transmission. When the LED diode is off, no signal is being transmitted. When the LED diode turns red, a signal is being transmitted.

Product Usage Instructions

To use the PK-305 Module, follow these steps:

1. Identify the desired function or device you want to control using the module.
2. Locate the corresponding ON and OFF buttons on the module.
3. To turn on the function or device, press the ON button associated with it. This will send a signal to activate the function.
4. To turn off the function or device, press the OFF button associated with it. This will send a signal to deactivate the function.

Note: The LED diode will indicate the status of signal transmission. If the LED diode is off, no signal is being transmitted. If the LED diode turns red, it means a signal is being transmitted.
