The Ubertooth One is an open source 2.4 GHz wireless development platform suitable for Bluetooth experimentation. Based on the powerful LPC175x ARM Cortex-M3 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.
