A home cluster consisting of 4 units in Raspberry Pi 4B!Try PoE Hat for Raspberry Pie 4B

Select PoE Hat for Raspberry Pi 4b

The current consumption of the Raspberry Pi 4B is 1 at the maximum of 1, according to the specifications published by the AO Data Equipment, a distributor..It will be 7A, but 3A or more is recommended when using a USB bus power device.

This is a guide when operating with PoE, but there are not many PoE Hat that meets these conditions, and there are few shops that have stock in Japan.

If you search, you will find a product made of uctronics, but unfortunately this time it was not available due to stock.

Therefore, I know the risk, and this time there are many types 2.I purchased a 5A compatible PoE Hat and tested it.Raspberry Pi 4B operation alone seems to be a problem, but when booting from USB SSD, the point is whether it can withstand the increase in current consumption that is added.

The following two products have been prepared.

In addition to the above, a PoE Hat for Raspberry Pi 3 Model B+purchased earlier is also prepared, but this is a Raspberry Pi 3b+exclusive and for the version before the circuit correction, and the USB output is low.For the time being, PoE could be supplied to the Raspberry Pi 4b itself, but the power supply to the USB SSD was unstable and did not work.See this sales page for details.

On the other hand, the TP-Link PoE 5-port switch "TL-SG1005P V1" was used on the power supply side.In this product, each port of 1 to 4 corresponds to PoE, and it is perfect for this 4 -car cluster configuration.The size is small and fits neatly on the bottom of the Geekpi case.

The power supply performance is up to 15 ports.4W has 56W abilities in total.The price was reasonable, and the selling price was 4500 yen.This would be just right for Raspberry Pi4 PoE operation.
