The Pidgeon 1 is a USB stick with CC1120 radio and CC1190 front end. This combo can put out 500mW transmit power at the lowest bandwidth of 8kHz. The radio is controlled by a STM32F051 microcontroller that is open for programming.

Unlike closed transceiver sticks, this device allows you to :

• Carefully control frequency, bandwidth, deviation and bitrate to achieve the best range in given environment.
• Select one of many modulations to fit your application, ranging from simplistic OOK or ASK, through standard FSK/GFSK, to less common spread spectrum or legacy analog.
• Integrate custom protocol or encryption into the physical layer of the data transmission.-
• Use received signal strength indicator (RSSI) for radio location or analysis of reflections in given environment.

Aim of the device is to allow access to the RF spectrum at elementary level to any desktop computer. Expansion of computer connectivity into 868MHz or 915MHz bands improves desktop engagement in "Internet of Things" applications.

Device offers 3 interfaces :

• USB connector used to connect to the host PC, where device is recognized as a virtual COM port (dedicated FTDI IC).
• SMA connector for RF input ( antenna ).
• RS485 interface.

User’s code is debugged over SWD interface which means the user needs ST-link for debugging ( any ST’s discovery kit would do ). In theory user can program the device via USB port (just program, not debug! ).

Device is tested to work on Windows and Linux machines, including distributions for ARM architecture. It has been tested to work for Raspbian and Debian. Which means this device can help you connect to your remote Raspberry Pi. You can also use SLIP or PPP protocols to allow this link to extend slow internet access over great line-of-sight range.

This kit contains pair of "Pidgeon 1" devices with antennas, necessary wires and STM32F0 discovery kit for programming. The Pidgeons come programmed with basic software allowing you to test their functionality.
