Product Description

Description:
The CY41 is an ASK/OOK compatible super heterodyne wireless receiving module with high performance for ISM frequency band. With the adoption of RF wireless data transferring/receiver chipset, the module has advantages at high receiving sensitivity, small size and low cost. It solves the problem on space for the small-sized product. From wireless signal input to data output can be done without any electrical circuit. User only use extra simple data decode circuit can achieve wireless products development.

 

Features:

1. Frequency: 433.92MHz;
2. High sensitivity -110dBm;
3. Supply voltage: 2.2V - 5.5V;
4. Low power consumption: 5V @ 433.92MHz, 4.6mA;
5. Data Rate: 2.4Kbps (Manchester Code);
6. Consumption on energy saving mode: min. 50nA;
