This is a development board for the mbed target board. Measuring 71mm x 61mm, the board offers an mini SD slot, USB A and B sockets as well as a ethernet port with tx/rx indicator LEDs. Revision B of this board fixes a few small niggles on the original, but is similar in every other respect.
The socket used to mount the mbed onto the board has an extra row of holes for each signal, meaning that probe wires can easily be attached to each pin of the mbed without soldering
