The evaluation board/kit (research and development board/kit) (hereinafter the “board”) is not a finished product and is as such not available for sale to consumers. The board is only intended

for research, development, demonstration and evaluation purposes and should as such only be used in laboratory/development areas by persons with an engineering/technical training

and familiar with the risks associated with handling electrical/mechanical components, systems and subsystems. This person assumes full responsibility/liability for proper and safe handling.

Any other use, resale or redistribution for any other purpose is strictly prohibited.
The board is delivered “AS IS” and without warranty of any kind including, but not limited to, that the board is production

worthy, that the functions contained in the board will meet your

requirements, or that the operation of the board will be uninterrupted or error free. ON Semiconductor expressly disclaims all warranties, express, implied or otherwise, including without

limitation, warranties of fitness for a particular purpose and non

infringement of intellectual property rights.

ON Semiconductor reserves the right to make changes without further notice to any board.
You are responsible for determining whether the board will be suitable for your intended use or application or will achieve your intended results. Prior to using or distributing any systems

that have been evaluated, designed or tested using the board, you agree to test and validate your design to confirm the functionality for your application. Any technical, applications or design

information or advice, quality characterization, reliability data or other services provided by ON Semiconductor shall not constitute any representation or warranty by ON Semiconductor,

and no additional obligations or liabilities shall arise from ON Semiconductor having provided such information or services.

was negligent regarding the design or manufacture of the board.
This evaluation board/kit does not fall within the scope of the European Union directives regarding electromagnetic compatibility, restricted substances (RoHS), recycling (WEEE), FCC,

CE or UL, and may not meet the technical requirements of these or other related directives.
FCC WARNING – This evaluation board/kit is intended for use for engineering development, demonstration, or evaluation purposes only and is not considered by ON Semiconductor to

be a finished end product fit for general consumer use. It may generate, use, or radiate radio frequency energy and has not been tested for compliance with the limits of computing devices

pursuant to part 15 of FCC rules, which are designed to provide reasonable protection against radio frequency interference. Operation of this equipment may cause interference with radio

communications, in which case the user shall be responsible, at its expense, to take whatever measures may be required to correct this interference.
ON Semiconductor does not convey any license under its patent rights nor the rights of others.
LIMITATIONS OF LIABILITY: ON Semiconductor shall not be liable for any special, consequential, incidental, indirect or punitive damages, including, but not limited to the costs of

requalification, delay, loss of profits or goodwill, arising out of or in connection with the board, even if ON Semiconductor is advised of the possibility of such damages. In no event shall

ON Semiconductor’s aggregate liability from any obligation arising out of or in connection with the board, under any theory of liability, exceed the purchase price paid for the board, if any.
