Marvin
Some kind of LoRa device http://www.rdmmakerspace.nl/Marvin/
Source code here: https://github.com/iotacademy/marvin
The device is a bare PCB with a USB on one end. Plugging this in to a computer shows up as a Arduino Leonardo and can be reprogrammed as such from the Arduino IDE. There is also a micro usb connection presumably connected to the lora module in some way.
Note that this version varies from original kickstarter project, it uses the Microchip RN2903 at 915 Mhz for US.
