			<pre>NOTE:
			PCIe 4.0 (fourth-generation) solid-state drives (SSDs) are typically designed to be backward compatible, meaning they can operate on lower PCIe versions such as PCIe 2.0 or 3.0. This backward compatibility means that even if the Raspberry Pi 5's PCIe interface only supports up to Gen 2.0, a PCIe 4.0 SSD can still function on a Gen 2.0 interface, but its speed will be limited to the rates of Gen 2.0.

			Specifically, the speed of a PCIe 4.0 SSD on a Gen 2.0 interface will be capped at about 5 GB/s (the theoretical maximum bandwidth of a PCIe 2.0 x1 interface), rather than the higher speeds achievable with a PCIe 4.0 x4 interface. Therefore, while PCIe 4.0 SSDs can be backward compatible with Gen 2.0, they cannot perform at their full potential on a Gen 2.0 interface.

	The Raspberry Pi 5 Expansion Board is a versatile accessory designed to enhance the capabilities of the Raspberry Pi 5 through a PCIe interface. This board not only provides a power conversion solution but also serves as a high-speed storage expansion device. It is equipped with a 20V Power Delivery (PD) input that converts the power supply to a stable 5.1V/5A output, ensuring reliable operation of the Raspberry Pi 5. The board requires a 20V PD-compatible power source for activation and can power both the Raspberry Pi and attached storage devices.
