Product Description

Description:
The CY31 is a super heterodyne wireless receiving module. This module adopts the industrial grade RF wireless data transmission receiving chip of European brand, which is a high performance of the receiving module of ISM frequency band. It has higher receiver sensitivity and stronger anti-interference ability. Any circuit that can be done without additional wireless signal input to the data signal output. Users only need to plus simple data decoding circuit, can easily achieve the development of wireless products.


 

Features:

1. High sensitivity: -112dBm;
2. Frequency: 315M/433.92MHz
3. Working voltage: VCC= 3.0-5.5 V;
4. Low Current: 4.2mA [email protected] / 4.5mA 5V@315MHZ
5. Operating Temperature:-20ºC~+70ºC, can work normally even in the harsh environment temperature.
6. Good selectivity and stray radiation inhibition ability, it's easy to go through the international standard such as CE/FCC.
7. The good radiation suppression ability, can work together with multiple receiving modules without interfering with each other

PRE-CAUTION:
The driven current of CY31 data output pin is weak, so if direct the single chip microcomputer, please don't add any pull up or pull down resistors on the MCU' I/O port.  The MCU internal pull-up and pull down resistors need to be in disabled state too.

PCB dimension has tolerance of 3%.
