ADD:The inventory has been sold out, and a new batch of goods inventory will be launched on February 5th.

Module characteristics

1. Radio Frequency Receiver Chip, commonly used in data transmission and control systems

2. It can run independently without external MCU control

3. Multichannel Transceiver@868MHz

4. Supporting FSK and bidirectional data transmission

5. The functions of interlocking, clicking and self-locking can be converted arbitrarily without jumping lines and can be stable for a long time.

6. Code learning without manual coding

7. Built-in memory, safe and reliable

8. Extra wide operating voltage

9. Distance, high reception sensitivity and anti-interference performance

10. Packet processing, including address recognition

Transmitting module

Mode conversion function: after pressing the learning button of the receiving module for 5 times, the red indicator on the receiving module flashes 8 times, the module switches from the receiving mode to the transmitting mode, and the red indicator on the receiving module flashes twice, indicating that the conversion is successful.

Matters needing attention:

RF devices are voltage sensitive devices. If the power supply is unstable or the ripple is large, please add a filter at the power input to ensure that the power supply voltage does not exceed the maximum working voltage of the product.

Ø This device is an electrostatic sensitive device, and anti-static measures must be taken during transportation and use.

Ø Make sure that the temperature does not exceed 245 ℃ when mounting.

Ø It is recommended not to use spring antenna with rubber in application to ensure better yield of products.

Ø This product manual is subject to change without notice.
