4 Port USB HUB HAT for Raspberry

4-Port USB 2.0 Expansion: Adds 4 downstream USB 2.0 ports to your Raspberry Pi, allowing simultaneous connection of multiple peripherals such as keyboards, mice, flash drives, and dongles.

USB to UART Onboard Converter: Features an integrated USB to UART converter (like the CP2102/CH340 chipset) with RX/TX indicators, enabling convenient serial debugging and terminal console access.

Flexible Host Connectivity: Connects directly to the Raspberry Pi's GPIO and USB port using a dedicated USB connector micro-bridge/pogo-pin layout or custom Micro-USB cable connection.

Onboard Power & Status LEDs: Equipped with multiple LED indicators for power status, USB port connection state, and serial UART data transmission monitoring.

Standard HAT Footprint: Designed to match the exact dimensions and mounting hole layout of standard Raspberry Pi HAT boards for secure standoff mounting.

PCB Construction: Built on a durable, multi-layer FR4 fiberglass circuit board engineered for steady power distribution across all downstream ports.

Connector Care: Insert USB peripherals gently and avoid applying vertical lever stress to USB-A sockets to prevent PCB trace fatigue.

Static Handling Precautions: Standard electrostatic sensitive device (ESD). Hold the board by its fiberglass outer edges and maintain grounding precautions during assembly.

Environmental Limits: Operating temperature range is $0^\circ\text{C}$ to $50^\circ\text{C}$. Protect from high humidity, conductive dust, and direct liquid contact while powered.

Essential Peripheral Expansion Pitch: Market heavily to users of compact boards like the Raspberry Pi Zero / Zero W / Zero 2 W who need additional full-sized USB-A ports for everyday desktop peripherals.

Serial Debugging Advantage: Emphasize the built-in USB-to-UART bridge as a key value-add feature for developers doing headless setups, custom firmware flashing, and low-level Linux debugging.

Recommended Cross-Sell Accessories: Pair with Brass Standoff Mounting Kits, Micro-USB Cable Sets, and USB WiFi / Bluetooth Adapters.

Universal Pi Compatibility: Highlight compatibility across the entire Raspberry Pi family, including Pi Zero series, Pi 3B+, Pi 4B, and Pi 5.
