Ubertooth One
Ubertooth One is the next generation hardware platform of Project Ubertooth.
It supersedes Ubertooth Zero and is currently the
preferred platform.
architecture
- RP-SMA RF
connector: connects to test equipment, antenna, or dummy load.
- CC2591
RF front end.
- CC2400
wireless transceiver.
- LPC175x ARM
Cortex-M3 microcontroller with Full-Speed USB 2.0.
- USB A plug: connects to host computer running Kismet or other host
code.
features
- 2.4 GHz transmit and receive.
- Transmit power and receive sensitivity comparable to a Class 1
Bluetooth device.
- standard Cortex
Debug Connector (10-pin 50-mil JTAG).
- In-System Programming (ISP) serial connector.
- expansion connector: intended for inter-Ubertooth communication or
other future uses.
- six indicator LEDs.
design
Ubertooth One was designed in KiCad, an open
source electronic design automation software package, with surface mount
components suitable for reflow.
pins and LEDs
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.
