This is an universal 868MHz-Transceiver (CC1101) including an ATMEL processor (ATMega32U2) for transparent data processing before passing through USB.

Be aware that this hardware processor (cmp to CUL V3) has limited RAM resources and may not allow you run all firmware features at once. You'll need gcc >= 4.5 and dfu-programmer >= 0.5.4 to program it. It's therefore not recommended for beginners!

For programming the device is equipped with an DFU-USB bootloader.

If required: you may solder a SMA connector.
