The Ubertooth One is an 2.4 GHz wireless development platform suitable for Bluetooth experimentation. Based on the powerful LPC175x ARM - microcontroller with full-speed USB 2.0, the Ubertooth One is a great way to develop custom Class 1 comparable Bluetooth devices.The entire board is only two and a half inches long with a USB-A connector at one end and an RP-SMA connector at the other.One thing that sets the Ubertooth apart from other Bluetooth development platforms is that it's capable of not only sending and receiving 2.4 GHz signals, can also operate in monitor mode, monitoring Bluetooth in real-time.This operating mode has been in low-cost WiFi modules for years and has found myriad uses in research, development and security auditing no such solution existed for the Bluetooth standard until now. Also, because it's a fully open-source platform (software and hardware), the schematics and code are readily available for all of your hacking needs.2.4 GHz Transmit and Receive.Transmit power and receive sensitivity comparable to a Class 1 Bluetooth device.Standard Debug Connector (10-pin 50- JTAG)In-System Programming (ISP) Serial ConnectorExpansion connector intended for -Ubertooth communication or uses.Six Indicator 2.4 GHz Duck Antenna IncludedColour:blackMaterial:Plastic + MetalPackage Contents:1 x Wireless Development Bluetooth Sniffer
