A radio module (receiver and transmitter) operating in the frequency range of 433 MHz, with the SPI communication interface. Powered with a voltage of 1.8 V - 3.6 V.Transmission distance: 300 - 500 meters (Depending on the specific situation of the environment and communication baud rate, etc.) The device has an external antenna that is connected to the SMA connector, the signals get transmitted and received on the goldin pin connectors.

Pins

The system has soldered SMA goldin pin connectors - a pitch of 2.54 mm. The description of the pins is presented in the array:

with this Module, we can Adjust the frequency (from 315 to 915), the modulation (Ask, fsk, etc), and tons of other parameters.

You can use smartRF (optional) to dive into parameters.

First, let's start with the pins of the cc1101.

This is How to connect Wireless Cc1101 Transceiver 433MHz Module with the Arduino:

To use the CC1101, you will need the panstamp library here.

Note that it will also work with the elechouse library here.
