CC1101 - USB - Lite module - Version 1

General

This “dongle” will enable you to interface with 868MHz air data of any kind. The module contains a modern 8-bit Atmel for raw data pre-processing before passing it to the USB 2.0 interface or the powerful Texas Instruments ISM-Transceiver.

To create your own applications you may use the avr-gcc.

The device ships with a DFU-bootloader. Use dfu-programmer to program it. Alternately you may solder an FPC-pinheader to use serial ISP programming.

By default an lambda/4 wire antenna is connected. Nevertheless: the PCB contains a SMA-antenna-pinheader, where you may solder a “real” antenna if required.
