Restrictions apply to this RF Equipment for use in Australia:

Only to be operated on 433Mhz / 915-930Mhz / 2.4Ghz (check the product description for compatible frequency ranges).
If operating outside of shared frequencies or in such a way that is beyond low interference potential devices are intended to function, then you have obtained the appropriate authorisation to do so.

For use in other locations around the world:

Follow region-specific frequency spectrum rules.

A declaration of use will need to be submitted during checkout.

This is a complete wireless transmitting and receiving kit, which can be applied to simple data wireless transmission, wireless remote control, anti-theft alarm system, etc. The kit has a simple structure and flexible application, and can be directly applied to the design and experimental development of various products.

The popular link is like this: MCU -> Encoder -> Transmitter ------ Receiver -> Decoder -> MCU. You can use this kit to build a system with other main control equipment, such as Arduino, Seeeduino XIAO, to implement applications such as wireless security alarms, remote control tools, and so on.

The following is the introduction of the transmitter and receiver respectively.

OOK (on-off keying) is binary switching keying. The modulation principle is to control the passage of the carrier by controlling the opening and closing of the switching device through the binary sequence, so as to load the binary signal onto the carrier. It is a low-cost and most easily implemented modulation method, which is widely used in various occasions.

Transmitter

In the wireless transceiver kit, the wireless transmitter module model is APF03, and its working voltage range is 3-12v. It adopts OOK modulation mode, which has the advantages of fast modulation rate and long transmission rate.

Receiver

In addition, the model of the decoding wireless receiving module is RXB28, and the working frequency between the transmitter and reciever is 315MHz or 433.92MHz, we are unable to guarantee which frequency is shipped. The recommended power supply input is 5V - the current can be as low as 4.2mA, and the power consumption is very low.

Features

Low power consumption: 3.3V about 3.8mA / 5V about 4.2mA(315MHz)
High receiving sensitivity: -109dBm@10kbps
Wide temperature range: -40°C ~ 85°C
Flexible application,breadboard and PCB friendly
Strong radiation suppression ability:no mutual interference, no influence on receiving distance.

Applications

Car remote control door switch (RKE)
Remote access control
Wireless security alarm
Remote control curtain machine
Wireless industrial controller
Wireless data transmission
Wireless remote control robot
