CC1101 is a low-cost sub 1GHz transceiver designed for low power wireless applications. The circuit is mainly used for Industrial, Scientific, and Medical (ISM) and Short Range Device (SRD) frequency bands running @ 315, 433, 868, and 915 MHz and can easily be programmed for running at other frequencies like 300 ~ 348 MHz, 387 ~ 464 and 779 ~ 928 MHz Band. CC1101 is an improved and code compatible version of the CC1100 RF TRX. The main improvements of the CC1101 include spurious response, enhance close-in phase noise, adjacent channel (ACP), higher saturation level, better output power ramping, and extended frequency bands of operation.

The module uses CC1100 Chip, running at 433 MHz , 868 MHz, 915 MHz of ISM Band, contains of a modulator a receiver with demodulator, power amp, crystal oscillator and regulator preamble and the CRC code generated automatically which can be easily configure through SPI (Serial Peripheral Interface).

PIN Configuration

  1. VCC > Power Input | 1.9v to 3.6v
  2. SI > Digital Input | Serial Configuration Interface, Data Input
  3. SCLK > Digital Input | Serial Configuration Interface, Clock Input / Data Output
  4. SO (GDO1) > Digital Output | Optional Output Test Signals
  5. GDO2 > Digital Output | FIFO Status Signals | Clear Channel Indicator | Clock Output, Down-Divided from   XOSC | Serial Output RX Data
  6. CSN > Digital Input > Serial Configuration Interface, Chip select Digital Output
  7. GDO0 > Digital I/O > Clock Output, Down Divided from XOSC, Serial Output RX Data, Serial Input TX Data, Analog Text I/O for Prototype / Production Testing
  8. GND > Ground Analog | Analog Ground Connection

Transmission distance: 300 – 500 meters (Depending on the specific situation of the environment and communication baud rate, etc.)
