Figure 16 Main Wi-Fi Board Components
5.1 Wi-Fi Board Block Diagram
Figure 17 shows the Wi-Fi board block diagram. Its main component is the GT202 module that incorporates the
QCA4002 SoC. The power options include USB and PMOD header. The 5V USB power is regulated to 3.3V with a
step-down converter to 3.3V. A dedicated jumper is used to select the desired power source.
Figure 17 Wi-Fi Board Block Diagram
The GT202 Wi-Fi module integrates the QCA4002 SoC on a carrier board which brings out three different host
connectivity options:
•
SPI interface through the PMOD connector – used for interfacing with the AE-CLOUD2 MCU board and power
supply source. This interface provides fast communication speed and access to the full networking functionality.
•
SDIO / UART interface – used for rapid prototyping and low communication speeds (not utilized by the AE-
CLOUD2 kit)
•
USB interface / Host-less – used for fast prototyping, diagnostic and alternative power supply (not utilized by the
AE-CLOUD2 kit)
