Notice applicable to Evaluation Boards according to European Regulation
For the European Regulation of the Evaluation Board, the applicable EU directives are considered, with aparticular attention to the Low Voltage Directive (LVD) 2014/35/EU, the Electromagnetic Compatibility (EMC)
Directive 2014/30/EU, and the Radio Equipment Directive (RED) 2014/53/EU. If the Evaluation Board is outside
the scope of the foregoing Directives, then the General Product Safety Directive (GPSD) 2001/95/EC and Council
Directive 93/68/EEC, amending Directive 73/23/EEC on electrical equipment designed for use within certain
voltage limits, are applicable.
The Evaluation Board meets the requirements of the Restriction of Hazardous Substances (RoHS 2 or RoHS
recast) Directive 2011/65/EU, Annex II, as amended by Directive 2015/863/EU.
Notice applicable to Evaluation Boards not FCC-Approved
This kit is designed to allow:
1.
Product developers to evaluate electronic components, circuitry, or software associated with the kit todetermine whether to incorporate such items in a finished product and2.
Software developers to write software applications for use with the end product.
This kit is not a finished product and when assembled may not be resold or otherwise marketed unless all
required FCC equipment authorizations are first obtained. Operation is subject to the condition that this productnot cause harmful interference to licensed radio stations and that this product accept harmful interference. Unlessthe assembled kit is designed to operate under part 15, part 18 or part 95 of 47 CFR, Chapter I (“FCC Rules”),
the operator of the kit must operate under the authority of an FCC license holder or must secure an experimental
authorization under part 5 of this chapter.
For Evaluation Boards annotated as FEDERAL COMMUNICATIONS COMMISSION (FCC) Part 15 Compliant•••

FCC Interference Statement for Class A Evaluation Boards: This equipment has been tested and foundto comply with the limits for a Class A digital device, pursuant to part 15 of the FCC Rules. These limits aredesigned to provide reasonable protection against harmful interference when the equipment is operated in
a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if
not installed and used in accordance with the instruction manual, may cause harmful interference to radio
communications. Operation of this equipment in a residential area is likely to cause harmful interference inwhich case the user will be required to correct the interference at his own expense.
FCC Interference Statement for Class B Evaluation Boards: This equipment has been tested and foundto comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits
are designed to provide reasonable protection against harmful interference in a residential installation.
This equipment generates, uses and can radiate radio frequency energy and, if not installed and used inaccordance with the instructions, may cause harmful interference to radio communications. However, there
is no guarantee that interference will not occur in a particular installation. If this equipment does cause
harmful interference to radio or television reception, which can be determined by turning the equipment off
and on, the user is encouraged to try to correct the interference by one or more of the following measures:–
Reorient or relocate the receiving antenna.
–
Increase the separation between the equipment and receiver.
–Connect the equipment to an outlet on a circuit different from that to which the receiver is connected.
–
Consult the dealer or an experienced radio/TV technician for help.
This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions:(1) This device may not cause harmful interference, and (2) this device must accept any interference
received, including interference that may cause undesired operation. Changes or modifications not expressly
approved by the party responsible for compliance could void the user's authority to operate the equipment.
