SKU: DFR1248
The LattePanda Iota 51W PoE Expansion Board is designed for LattePanda Iota, compliant with IEEE 802.3bt, offering up to 51W power. It enables 12V DC power and Gigabit network via one Ethernet cable (with a PoE switch/router) and has an independent Gigabit port for dual Ethernet—ideal for industrial automation, edge computing. Warning: PoE power may carry 50V DC; avoid touching exposed circuits when powered!
| Parameter | Specification |

| Label | Interface | Function Description |
|---|---|---|
| 1 | PCIe 3.0 x1 FPC Connector | Connects to LattePanda Iota's 16-pin FPC interface for communication with the RTL8111H network chip |
| 2 | 4-pin Power Output Interface | Supplies 12V DC power to the LattePanda Iota |
| 3 | 12V DC Power Terminal Block | Output terminal for powering external devices |
| 4 | RJ45 Port | Gigabit Ethernet port supporting PoE input |
| Notice | Description |
|---|---|
| ✅ Must use IEEE 802.3bt equipment | Using lower-standard PoE sources (e.g., 802.3af/at) may result in insufficient power, causing reboots or shutdowns |
| ? Inductor heating is normal | The silver inductor labeled "100" may get slightly warm under light loads due to SSR FPWM mode; this is normal, not a fault |
| ⚠️ Only expansion board port supports PoE | The native Ethernet port on the LattePanda Iota does not support PoE input—do not confuse the two |
| ? External power output | The 12V terminal block can power external devices (up to 51W); ensure proper load matching |
Compatible Only With: ✔️ LattePanda Iota
