I Product Overview
Raspberry Pi 5 PCIe to M.2 & SFP Gigabit OpticalAdapter Board Compatible with 2280/2260/2242/2230 Size NVMe SSDs, HAT+ Standard
This is a multi-functional PCIe HAT+ expansion board specially designed for Raspberry Pi 5. Equipped with the ASM1182e PCIe expansion chip, it splits the single PCIe interface of Raspberry Pi 5 into two independent PCIe lanes, which are used for connecting M.2 NVMe SSD and Gigabit Ethernet controller respectively, enabling dual functions of M.2 solid-state drive expansion and Gigabit SFP fiber communication.
It supports M.2 NVMe SSDs in multiple form factors including 2280, 2260, 2242 and 2230. It is widely applicable for system boot drives, data storage, lightweight NAS, edge computing gateways, industrial communication and long-distance network transmission scenarios.
For network connection, it adopts RTL8111H + RTL8213B solution, and supports Gigabit fiber network communication via standard SFP port with optical modules installed. Onboard EEPROM chip and 2×20Pin header are designed in compliance with Raspberry Pi HAT+ specifications, allowing Raspberry Pi 5 to automatically recognize the board and complete relevant configurations easily.
