Single-board pc accent maker 52Pi has introduced a brand new model of its “Product W01” add-on board for the Raspberry Pi 5 — doubling as much as two 2.5-gigabit-Ethernet ports, alongside an M.2 M-key slot for Non-Risky Reminiscence Categorical (NVMe) storage or different PCI Categorical units: the U2500 HAT.
“This HAT board is a superb addition to any Raspberry Pi setup,” 52Pi claims of its newest {hardware} launch, “providing a handy approach to enhance each storage and networking capabilities in a single, compact package deal. The Raspberry Pi HAT ({Hardware} Connected on High) board […] is a flexible enlargement module designed to reinforce the capabilities of your Raspberry Pi 5.”

The U2500, dropped at our consideration by Linux Gizmos, is not 52Pi’s first shot at placing 2.5-gigabit-Ethernet connectivity onto a Raspberry Pi 5: again in Could the corporate confirmed off the “Product W01” U2500, which — like the brand new U2500 — featured an M.2 slot related to the Raspberry Pi 5 over PCI Categorical (PCIe) plus a 2.5-gigabit-Ethernet port related over USB 3.0.
Product W01, nevertheless, has disappeared from the corporate’s website — and the brand new U2500 is as an alternative. The general design is essentially unchanged: there’s nonetheless a single M.2 M-key slot supporting 2230- and 2242-footprint NVMe drives and different PCI Categorical units, although it loses assist for bigger 2260- and 2280-footprint units, and the Ethernet remains to be related over USB 3.0. This time, although, there’s not one Ethernet port however two — each supporting 2.5-gigabit-Ethernet connectivity, and each usable similtaneously the Raspberry Pi 5’s on-board gigabit Ethernet port.

To forestall bottlenecks, the brand new U2500 design connects one Ethernet port per USB port — which means that it takes up the entire Raspberry Pi 5’s two USB 3.0 ports, leaving solely the slower USB 2.0 ports accessible for different equipment. This additionally means, although, that the 2 Ethernet ports run independently with out sharing bandwidth — maximizing efficiency.
A doubling of community ports has, nevertheless, come at a price: the U2500 is up on the market on the 52Pi retailer now at $49.99, up from the $29.99 of the single-port Product W01.
