This external wireless antenna module CC1101 is suitable for Funduino and Arduino projects.
The CC1101 module of 1.2K baud consists of a domestic R & Lotes unit to improve the effective communication distance.
This is a significant improvement over the CC1100 module.
It allows to adjust the speed of the bits for different uses, thus allowing a higher transmission speed.
Supports 2-FSK, GFSK and msk modulations. It also has a high sensitivity (1.2kbps @>
