3.0 HARDWARE SETUP
To set up the evaluation hardware, perform the following steps:
1. Connect the min-USB cable to your computer’s USB port and to the evaluation board’s
UART connector. This connection provides power to the board and provides a data con-
nection to the command console.
2. Note the COM port to which you have attached the cable.
3. Connect the portable mini-speaker 3.5 mm TRR plug to the stereo audio out connector
(J9). The mini speakers are powered via USB.
Figure 1-2 shows the completed hardware setup for the evaluation board.

Note: Windows should automatically install the drivers for the cable. If it does not, down-
load and install the FTDI drivers from the Support page on the Roving Networks
website at http://www.rovingnetworks.com/support.php.
CAUTION
Roving Networks recommends that you connect the RN-52-EK evaluation board and
min-speakers to different USB sources to avoid a ground loop that causes noise in the
audio output.
