Open Hardware project which can both transmit and receive at 2.4GHz with suitable transmit power and receive sensitivity. A suitable antenna should be affixed to the female RP-SMA port. A 2.4GHz 'rubber duck' style antenna is included, along with an RP-SMA to SMA adapter so you can attach other SMA antennas of your choosing Contains a standard serial debug connector (10-pin 50- JTAG) for in-system programming (ISP) Also contains an expansion connector intended for -Ubertooth communication and uses. The an open source 2.4 GHz wireless development platform suitable for 2.4GHz experimentation. Based on the powerful LPC175x ARM -M3 microcontroller with full-speed USB 2.0, the Ubertooth One is a great way to develop custom Class 1 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 apart from other 2.4GHz development platforms is that it's capable of not only sending and receiving 2.4 GHz signals, but can also operate in monitor mode, monitoring traffic in real-time. This operating mode has been present in low-cost WiFi modules for years and has found myriad uses in research, development and security auditing but no such solution existed for 2.4GHz standards 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. colour:black Material:PCB size:61.75mm x 19mm Package Contents: 1*Ubertooth One module test tool Only the above package content, other products are not included.
