3. Kit Operation

This chapter introduces you to the CYW943907AEVAL1F EVK and the features that will be used as part of the kit operation.
Features such as Wi-Fi connection and programming/debugging are discussed in this chapter. The chapter also describes
the USB-UART bridge that can be used to communicate with the CYW43907 device on this EVK.

3.1 Theory of Operation

Figure 3-1 shows the block diagram of the CYW943907AEVAL1F EVK. This board contains a BCM943907/CYW43907-based
System in package (SiP), which is a Murata Type1GC wireless module. This module is an embedded network controller
solution from Murata. This board also contains a USB-Serial interface, JTAG programmer, and a debugger.
This board features Arduino form-factor-compatible headers that enable Arduino shields to be plugged on top, extending its
capabilities. This board also features two user switches, two user LEDs, an RJ-45 connector for Ethernet, and a reset switch
for the wireless module.

3.2 Onboard Programmer/Debugger and Serial Interface Chip

An FT-2232-HQ chip is used for onboard programming, debugging, and USB-Serial functionality. It connects to the computer
over a USB interface and connects to the CYW43907-based SiP module over JTAG and UART pins.
