LORDWORLD PoE Expansion Board for RDK X5 802.3af/at 25W 40-pin development board

SKU CH-B7QY-QP7AS

A PoE expansion board powers the RDK X5 over Ethernet with up to 25 W, adds 5 V and 12 V outputs, and includes a fan, heatsink, and stackable 40-pin header

  • Single-cable power and data via 802.3 PoE
  • Active fan and metal heatsink keep temperatures stable
  • 5 V and 12 V rails deliver up to 4.5 A combined
  • 40-pin pass-through header allows board stacking
  • High-efficiency buck converter supports 25 W output

PoE Power for RDK X5

This expansion board supplies power and network connectivity to the D-Robotics RDK X5 through a single Ethernet cable. It complies with IEEE 802.3 af/at standards and adds a stackable 40-pin GPIO header so developers can attach further accessories without losing pin access. The design targets IoT edge projects that need a tidy, cable-reduced deployment.

25W Output With Dual Voltage Rails

The onboard switching regulator delivers up to 25W combined across 5V and 12V rails, rated at 4.5A total current. This headroom covers the RDK X5 plus typical sensors, actuators or small displays. Loads that exceed the 25W ceiling or demand sustained peaks beyond the converter rating will require an external supply instead.

Active Cooling For Sustained Loads

An integrated fan and aluminium heatsink dissipate heat from the buck converter during high-current operation. The forced-air solution keeps temperatures stable when the board runs near its 25W limit, avoiding thermal throttling. Under light loads the fan runs quietly, and power draw remains limited to the PoE input budget.

Questions about this item

Will the 40-pin GPIO pass-through header still let me stack my existing RDK X5 HATs on top of this PoE board?

Yes, the board includes a standard 40-pin stackable GPIO header designed to pass signals through so you can mount additional RDK X5 expansion boards above it.

How can I confirm the 802.3af/at PoE module is delivering the full 25 W to my RDK X5 and peripherals after installation?

Measure the 5 V and 12 V output rails under load; the onboard buck converter supports up to 4.5 A combined across both rails with a 25 W ceiling when the fan and heatsink are operating.

Does the package include the Ethernet cable and RDK X5 board, or do I need to source them separately?

Only the PoE expansion board with its integrated cooling fan and metal heatsink is supplied; the RDK X5 compute module and Ethernet cable must be purchased separately.
