  • Page 5 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.

  • Page 6: Introduction

    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.
