4Ch Wireless RF Remote Control Transceiver Module YK04

4Ch Wireless RF Remote Control Transceiver Module YK04 is an 4 Channel Wireless Four Button RF Remote Control Transmitter Receiver Module with Non-Locking mode can be composed of a fixed code four radio receiver circuits, remote control of four four-bit data output code corresponding to the module, you can easily make up a wireless remote control receiver circuit.

They are widely applied in the majority home electronics enthusiasts, industrial remote control electronic product design and development can be very good as a single-chip signal input source, especially for students and colleges electronic circuit design, the graduate design of the remote control circuit portion.

Features of 4Ch Wireless RF Remote Control Transceiver Module YK04:

• No. of channels 4
• Operating mode Non-Locking
• Operating voltage DC 12V(Inbuilt 27A / 12V battery x 1)
• Operating current 10mA at 12V.
• Radiated power 10mW at 12V
• Transmission distance (m) 3 to 5 (open field, the receiver sensitivity of -100dbm)
• Transmitting frequency 315MHZ.

There are four buttons on the remote control and respectively correspond to the four data bits to the receiving board output pin D0, D1, D2, and D3.

Press the buttons to transmit signals, the corresponding data bit is output high.

Caution: Take care while handling the receiver module, that onboard copper coil (inductor) should be untouched. A little physical movement to the coil changes the inductance value which may cause the inappropriate circuit functioning

Working Principle 4Ch Wireless RF:

When a key is pressed, the IC is connected to power supply battery and it starts transmitting packets at 315 Mhz frequency consisting of its ID and Data byte which indicates which key was pressed. This information is used in remote control applications.
Each transmitter has a pre-programmed unique ID set during manufacturing and cannot change. The receiver board usually stores the transmitter ID in its memory, meanwhile the receiver only responds to known transmitter IDs for secure applications.
The RF part inside remote is SAW based 315 Mhz transmitter.

Note: By default, this remote control module comes with a Non-Locking mode.

Package Includes: 4Ch Wireless RF Remote Control Transceiver Module YK04 Set x 1 Piece.
