Meet the Ubertooth One! The Ubertooth One is an open-source wireless development platform operating at 2.4GHz, designed primarily for Bluetooth experimentation.

The Ubertooth One is quite small at just 2.5" in length. The antenna input is RP-SMA (note: this is NOT the same as SMA!) to ensure compatibility with a wide-range of commercially available 2.4GHz antennas. Of course, a suitable 'rubber ducky' antenna is included at no extra charge to ensure you have everything you need to get started right away!

The PC interface is full-speed USB 2.0, controlled by a powerful Cortex-M3 microcontroller (LPC175x).

This device will not only allow you to receive AND transmit 2.4GHz signals, but will also allow you to monitor external Bluetooth traffic, all in real-time! This is a fantastic development for Bluetooth developers and security researchers.

Features:

TX & RX capable with transmit power and receive sensitivity similar to other class-1 Bluetooth devices.
Open-source, open-hardware design
Included 2.4GHz RP-SMA antenna
10P JTAG connector for debugging
ISP connector for in-system programming
Additional expansion connector for connecting to a second Ubertooth
Dimensions: 61.75mm x 19mm (2.43" x 0.75")

Design:

Ubertooth One was designed in KiCad, an open source electronic design automation software package, with surface mount components suitable for reflow.

Ubertooth One diagram

This diagram shows the location of LEDs and the pins of the expansion connector.

LED guide:

RST: indicates that the LPC175x is powered on. This should always be on during operation except during a full reset of the LPC175x (e.g., while entering ISP mode).

1V8: indicates that the CC2400 is being supplied with 1.8 V. Control of this supply depends on firmware. 1V8 power is required to activate the crystal oscillator which is required to activate USB.

USB: indicates that USB has passed enumeration and configuration.

TX: Control of this LED depends on firmware. It typically indicates radio transmission.

RX: Control of this LED depends on firmware. It typically indicates radio reception.

USR: Control of this LED depends on firmware.

The TX, RX, and USR LEDs blink in a distinctive chasing pattern when the bootloader is ready to accept USB DFU commands.
