WIZPoE-P1 Overview
A PoE PD module extracts DC power carried on the Ethernet cable from a PoE switch (endspan) or PoE injector (midspan) and converts it to a low-voltage rail that powers an edge device. Within the power-management hierarchy, it spans the PD interface, classification, isolation, and DC-DC conversion stages in one package, eliminating a separate AC-DC adapter and power cable for networked devices.
Key features include IEEE 802.3af compliance, support for both Mode A (Endspan, power on pins 1,2+/3,6-) and Mode B (Midspan, power on pins 4,5+/7,8-), a wide 40Vdc to 60Vdc input range, and two internal bridge rectifiers that auto-adapt to either mode. PoE transmission reaches up to 100 meters.
Technically, the module integrates a high-efficiency switching DC-DC converter operating at a 280 kHz to 320 kHz switching frequency, achieving 70% to 90% conversion efficiency at 80% load. Galvanic isolation protects the host electronics from Ethernet-cable voltage surges and ground-potential differences. WIZnet states the 7W output covers the power needs of more than 90% of wireless network access points, network video phones, and network advertising systems.
Typical applications include small-scale IoT nodes, IP cameras and network video phones, wireless access points, and advertising displays where a single CAT5 cable must carry both data and power.
Designers should budget for converter efficiency and thermal rise inside the enclosure, and verify that the host load stays within the 7W budget because an IEEE 802.3af PD class guarantees only up to 12.95W at the PSE side before cable and conversion losses.

Typical Applications
WIZPoE-P1 is suitable for 6 applications: Wireless Access Points, Network Video Phones and IP Cameras, Network Advertising and Digital Signage Displays, Small-Scale IoT Devices and Smart Building Nodes, Raspberry Pi and Single-Board Computer PoE Power, Industrial Networked Equipment.
Wireless Access Points
Wireless access points are the flagship application named by WIZnet for the WIZPoE-P1, which the manufacturer states covers the consumption requirements of more than 90% of wireless network access points on the market. The 5V DC, 7W output directly powers the SoC, RF front end, and Ethernet PHY of small-form-factor APs, while the 40Vdc to 60Vdc input with Mode A/B adaptive bridge rectifiers accepts power from any IEEE 802.3af switch or midspan injector up to 100 meters of cable. Isolation protects the AP electronics from cable surges. Place a bulk input capacitor at the module input and keep the load within 7W to stay inside the 802.3af class budget.

Network Video Phones and IP Cameras
Network video phones and IP cameras are explicitly cited by WIZnet as target applications for the WIZPoE-P1. A single CAT5 cable carries both data and up to 7W of power, eliminating local AC adapters in ceiling or wall deployments. The module's isolation version protects camera sensor and processor circuitry from ground-potential differences between the PoE switch and the camera housing, a common failure source in outdoor surveillance. With 280 kHz to 320 kHz switching and 70% to 90% efficiency at 80% load, thermal rise stays manageable in sealed camera enclosures. The 5V rail suits typical image-sensor SoCs; add local LDO post-regulation for noise-sensitive analog front ends.

Network Advertising and Digital Signage Displays
WIZnet lists network advertising systems among the primary applications of the WIZPoE-P1. Small signage displays, shelf-edge labels, and advertising players benefit from single-cable deployment: data for content updates and 7W of power from the same Ethernet run, with the module adapting automatically to Mode A (endspan) or Mode B (midspan) PSE wiring through its internal two-channel bridge rectifiers. The 38 x 16 x 13 mm package fits slim display housings, and the 100-meter PoE reach covers typical retail floor distances. Designers should verify that panel backlight and logic loads remain within the 7W budget and allocate airflow or copper pour for module self-heating.

Small-Scale IoT Devices and Smart Building Nodes
WIZnet positions the WIZPoE-P1 as ideal for powering small-scale IoT devices over Ethernet without a separate power cable. Smart-building nodes - occupancy sensors, access-control panels, environmental monitors - deploy wherever structured cabling exists, and the module turns any 802.3af port into a 5V, 7W power outlet at up to 100 meters. The 40Vdc to 60Vdc input tolerates normal PoE voltage droop over long cable runs, and isolation simplifies compliance in mixed-voltage panels. A typical node pairs the module with a WIZnet hardwired Ethernet controller for the data path, reserving the 7W budget for the MCU, sensors, and local actuators or relays.

Raspberry Pi and Single-Board Computer PoE Power
The WIZPoE-P1's regulated 5V DC output maps directly to Raspberry Pi and other single-board computer power inputs, making it a practical PoE splitter for SBC-based projects such as kiosks, edge-AI sensors, and media players. IEEE 802.3af Mode A/B adaptive input means any compliant PoE switch or injector powers the board, with up to 7W available - sufficient for Pi-class boards in headless or light-peripheral configurations, though not for heavily loaded SBCs that need PoE+ (802.3at). The isolated topology protects the SBC from cable transients in distributed installations. Distributors including The Pi Hut stock the module specifically for the maker and SBC community, simplifying prototype sourcing.

Industrial Networked Equipment
Mouser classifies the WIZPoE-P1 as an industrial-grade Power over Ethernet module, fitting factory-floor equipment such as Ethernet-attached sensors, I/O modules, and monitoring nodes. The wide 40Vdc to 60Vdc input handles PoE PSE voltage variation, and the isolated DC-DC design (70% to 90% efficiency at 80% load, 280 kHz to 320 kHz switching) provides galvanic separation between the noisy plant network and sensitive control electronics. Mode A/B adaptivity means the module works whether power originates from an endspon switch or a midspan injector. For industrial designs, derate the 7W output for high ambient temperatures and ensure conformal coating compatibility of the module assembly.

Design Notes
Budget the load strictly within the 7W output rating. IEEE 802.3af guarantees only up to 12.95W at the PSE side; cable losses plus the module's 70% to 90% conversion efficiency (at 80% load) reduce the usable output. Estimated: at 7W out and 85% efficiency, input draw is about 8.2W and the module internally dissipates roughly 1.2W. If your host needs more than 7W, move to an 802.3at (PoE+) class solution rather than overloading the module.
Estimated: at full 7W output and 85% efficiency, about 1.2W is dissipated inside the 38 x 16 x 13 mm module. In sealed enclosures (outdoor cameras, ceiling APs, signage housings) without forced airflow, verify the internal ambient stays within the module's rated operating temperature; add copper pour under the module or ventilation slots if the enclosure is small. Measure module surface temperature at max load and max cable length (100 m) during design validation, since long cables slightly raise input current and losses.
Two datasheet revisions exist: an earlier non-isolated version and the current isolated version of the WIZPoE-P1. Confirm you are designing against the isolation-version datasheet (hosted on docs.wiznet.io) before layout, because topology and safety characteristics differ. Also confirm Mode A/B behavior is handled by the internal 2-channel bridge rectifiers and do not add external steering diodes that drop input headroom below the 40Vdc minimum under long-cable droop.
Compliance Information
Compliance to IEEE 802.3af is confirmed in manufacturer data. RoHS/REACH/lead-free status was not stated in the retrieved web data and must be confirmed with WIZnet or the distributor.
