5 Evaluation Kit Overview
The LM10500 evaluation boards can operate standalone, communicate to a USB2PWI interface board, or to
an external AVS primary. The USB2PWI interface board and a graphic user interface (GUI) are included in the
evaluation kit to easily evaluate the LM10500 AVS functionality from a PC. The evaluation kit is consist of:
• LM10500 evaluation board, as shown in
• USB2PWI interface board, as shown in
• 5-pin mini USB cable
• A CD, including:
– LM10500 evaluation GUI
– LM10500 data sheet
– LM10500 evaluation board user's guide (this document)
There are two versions of LM10500 evaluation board: LM10500SQ-0.8EV and LM10500-1.0EV. The differences
