Ubertooth Zero was the first working prototype hardware platform of Project Ubertooth. It has been superseded by Ubertooth One.



  • RP-SMA RF connector: connects to test equipment, antenna, or dummy load.

  • CC2400 wireless transceiver IC.

  • LPC175x ARM Cortex-M3 microcontroller with Full-Speed USB 2.0.

  • USB A plug: connects to host computer running Kismet or other host code.


  • 2.4 GHz transmit and receive.

  • Transmit power and receive sensitivity comparable to a Class 3 Bluetooth device.

  • Non-standard JTAG connector.

  • In-System Programming (ISP) serial connector.

  • Expansion connector: intended for inter-Ubertooth communication or other future uses.

  • Six indicator LEDs.


Ubertooth Zero was designed in CadSoft EAGLE with surface mount components suitable for reflow.


Michael Ossmann presented Ubertooth Zero, a preview (video: part 1, part 2) at ToorCon 12 in October, 2010.
