Product Topology: Product topology is an important section of the datasheet and a combination of two elements: the diagram with the main components references, and the table listing and describing those main components. It is important to describe only the components interesting for the final user, so capacitors, resistors and other passive components should not be described in this section as a general rule.

The GIGA R1 WiFi's main processor is the dual-core STM32H747 (U1) including a Cortex® M7 running at 480 MHz and a Cortex® M4 running at 240 MHz. The two cores communicate via a _Remote Procedure Call_ mechanism that allows calling functions between each processor seamlessly.
370
+
<pstyle="text-align: justify;">The High-Density connectors (J1-J2) provide connectivity with the Portenta family boards. For detailed information, refer to the Portenta Hat Carrier pinout and the respective documentation for the Portenta family boards. In Figure 6, the Portenta X8 board High-Density connectors pinout is shown as an example.</p>
The Murata® LBEE5KL1DX-883 wireless module (U5) simultaneously provides Wi-Fi® and Bluetooth® connectivity in an ultra-small package based on the Cypress CYW4343W. The IEEE802.11 b/g/n Wi-Fi® interface can be operated as an access point (AP), station (STA) or as a dual mode simultaneous AP/STA and supports a maximum transfer rate of 65 Mbps. Bluetooth® interface supports Bluetooth® Classic and Bluetooth® Low Energy. An integrated antenna circuitry switch allows a single external antenna (J14) to be shared between Wi-Fi® and Bluetooth®.

Two USB ports are provided on the Arduino GIGA R1 WiFi. One USB 2.0 type A (J2) and a USB-C® (J12). The USB 2.0 connector allows external devices to be connected as peripherals, while the USB-C® connector allows the GIGA board to be connected as a peripheral for other devices. Note that super speed pins on the USB-C® connector (J12) are unpopulated. A TVS diode array is placed on the VBUS of each connector (D4, D2) for ESD protection purposes.

The STM32H7 (U1) has two digital-to-analog converters (DAC) which drive the stereo audio output on the 3.5 mm jack connector (J15). Each DAC has a resolution of up to 12 bits. The right and left channels are also accessible via pins DAC0 and DAC1 respectively. A microphone input is also present on the jack connector (J15), which is shared with analog pin A7. The _Buffered mode_ in the STM32H7 can allow for low-impedance output while _Sample and hold_ functionality can help to reduce power consumption. Up to 10 mega samples per second are supported.

Power can either be supplied via the VIN pins, or the 5V of the USB connectors (J2, J12). If power is supplied via VIN, the MP2269GD-Z (U7) buck converter steps the voltage down to 5V. The 5V power rail is then stepped down to 3.3V by the MP2322GQH (U6) buck converter. The logic level of components on the Arduino GIGA R1 WiFi is 3.3V.
