Description

BPI-F3 PoE module (BPI-5400B): power the Banana Pi BPI-F3 over Ethernet

The BPI-5400B is a 30 W isolated PoE module from the BPI-5400 series, in its 12 V variant (marked RT5400B), intended for the Banana Pi BPI-F3. Banana Pi designed it for the Banana Pi BPI-F3, the eight-core SpacemiT K1 RISC-V board: once soldered onto the board, it powers it through the RJ45-2 port from a switch or injector IEEE 802.3af / 802.3at.

Highlights

30 W maximum output power.
36 to 57 V input, the range of standard PoE equipment.
1,500 V transformer isolation between input and output.
Built-in rectifier bridge on the 5400B version (the 5400BS does not have one).
High-efficiency DC/DC converter, low noise and short-circuit protection.

Technical specifications

Element	BPI-5400B (12 V)
Standards	IEEE 802.3af and IEEE 802.3at
Input	36 to 57 V
Rated output	12 V, 30 W maximum
Insulation	1,500 V
Rectifier bridge	Built-in
Housing	DIP, recommended hole size 1.2 mm
Pins	VA1, VA2, VB1, VB2, external capacitor, -VDC, +VDC, ADJ adjustment
Target board	Banana Pi BPI-F3, RJ45-2 port

Which one should you choose?

Module	Target board	Output	Insulation	Assembly
BPI-5400B	BPI-F3	12 V, 30 W max	1,500 V	to be soldered
BPI-7402	BPI-R64	12 V / 2 A, 30 W max	1,000 V	R64 PoE interface

Both modules have the same power, but each one matches the pinout and mounting location of its own board.

Compatibility and pitfalls to avoid

Soldering required : Banana Pi states that the RT5400B module must be soldered onto the F3. It is not a plug-in module.
Correct variant : the series exists in 12 V and 24 V; the F3, powered at 12 V, requires the 12 V version.
RJ45-2 port only : power arrives through the F3’s second Ethernet port, not the first.
PoE source required : 802.3af/at switch or injector. To draw 30 W, choose an 802.3at source.
Power budget : the F3 can host an SSD, a modem and USB 3.0 peripherals; above 30 W, go back to a conventional power supply.

Step-by-step setup

Work with the board powered off, on an antistatic surface, with a soldering iron suited to through-hole components.
Place the RT5400B module on the dedicated footprint near the RJ45-2 port and solder its pins; the external 22 to 100 µF 63 V capacitor required by the datasheet must be fitted.
Visually check the solder joints, then connect the RJ45-2 port to an 802.3af/at source.
On first boot, disconnect any other power supply to confirm operation on PoE alone.

If you are not comfortable with soldering, have the work done by an electronics workshop: a mistake on a circuit powered at 48 V can damage the board.

Recommended accessories

TP-Link 4-port PoE+ switch : 802.3at source for the F3.
Raspberry Pi PoE+ Injector : 30 W 802.3af/at on a single port (C13 cord not included).
RJ45 CAT6 Ethernet cable : to connect the PoE source to the RJ45-2 port.

Uses

BPI-F3 as a gateway or RISC-V compute node installed far from a power outlet.
Several boards powered from a single switch in a test rack.

Frequently asked questions

Is the BPI-5400B compatible with the BPI-F3?

Yes, it is the RT5400B module that Banana Pi specifies for adding PoE to the F3, via its RJ45-2 port.

Does the module need to be soldered?

Yes, the Banana Pi documentation specifies that it is soldered onto the board.

How much power does it provide?

Up to 30 W at 12 V output, with an 802.3at source.

Can it be used on another board?

This module is offered here for the F3. Banana Pi also mentions the RT5400B for custom network boards, but this requires hardware modifications.

Which PoE source should I use?

An 802.3af or 802.3at compliant switch or injector delivering 36 to 57 V.

Does PoE replace the F3’s usual power supply?

Yes, as long as total consumption stays below 30 W. With an NVMe SSD, a modem and several powered USB peripherals, measure actual consumption before removing the 12 V power adapter.

Does the RJ45-2 port keep its Gigabit speed?

Yes, PoE carries power over the same cable without replacing the port’s Gigabit data link.
