Safety Information
The CYW954907AEVAL1F EVK is intended for use as a development platform for hardware or soft-
ware in a laboratory environment. The board is an open-system design, which does not include a
shielded enclosure. Due to this reason, the board may cause interference with other electrical or
electronic devices in close proximity. In a domestic environment, this product may cause radio inter-
ference. In such cases, take adequate preventive measures. Also, do not use this board near any
medical equipment or RF devices.
Attaching additional wiring to this product or modifying the product operation from the factory default
may affect its performance and cause interference with other apparatus in the immediate vicinity. If
such interference is detected, suitable mitigating measures must be taken.
General Safety Instructions
ESD Protection
ESD can damage boards and associated components. Cypress recommends that the user perform
procedures only at an ESD workstation. If an ESD workstation is not available, use appropriate ESD
protection by wearing an antistatic wrist strap attached to the chassis ground (any unpainted metal
surface) on the board when handling parts.
Handling Boards
CYW954907AEVAL1F boards are sensitive to ESD. Hold the board only by its edges. After remov-
ing the board from its box, place it on a grounded, static-free surface. Use a conductive foam pad if
available. Do not slide the board over any surface. Any physical action on CYW954907AEVAL1F
such as changing wires, jumper settings, or measuring voltages can cause stress on the
CYW954907AEVAL1F printed circuit board assembly (PCBA). You must ensure that the PCBA has
proper support on the bottom side to avoid stress on the PCBA when the EVK is in operation.
The CYW954907AEVAL1F contains electrostatic discharge (ESD)-sensitive devices.
Electrostatic charges readily accumulate on the human body and any equipment, and can
discharge without detection. Permanent damage may occur on devices subjected to high-
energy discharges. Proper ESD precautions are recommended to avoid performance
degradation or loss of functionality. Store unused CYW954907AEVAL1F in the protective
shipping package.
End-of-Life/Product Recycling
This kit has an end-of-life cycle of five years from the year of manufacturing mentioned
on the back of the box. Contact your nearest recycler for discarding the kit.

1. Introduction
Thank you for your interest in the CYW954907AEVAL1F Evaluation Kit (EVK). The CYW954907AE-
VAL1F EVK enables customers to evaluate and develop single-chip Wi-Fi applications using
CYW54907 devices.
The CYW954907AEVAL1F EVK uses WICED Studio 6.0 (or later) to develop and debug your
CYW54907 project. CYW954907AEVAL1F EVK offers footprint-compatibility with Arduino shields. In
addition, the kit features an RJ-45 Ethernet connector, and onboard programmer/debugger and
serial bridge chip. The CYW954907AEVAL1F EVK supports only 3.3 V as the operating voltage.
WICED Studio 6.0 (or later) supports application development using a WICED development board
(CYW954907AEVAL1F). The development system is compatible with the Windows, OS X, and Linux
operating systems. This document provides instructions for utilizing peripherals, such as I2C or SPI,
in WICED sample applications using the WICED Studio Integrated Development Environment (IDE).
Note: This document applies to WICED Studio 6.0 (or later).
The CYW954907AEVAL1F EVK is available through the Cypress Online Store or through our distrib-
utors.
