51W PoE Expansion Board for LattePanda IOTA (IEEE 802.3bt)

The LattePanda IOTA 51W PoE Expansion Board is a high-performance power and network solution engineered specifically for the LattePanda IOTA single-board computer. It operates on the IEEE 802.3bt (PoE++) standard, enabling the delivery of up to 51W of power and Gigabit Ethernet data through a single Ethernet cable. This design dramatically simplifies system deployment by eliminating the need for a separate power adapter for the main board and its connected peripherals. With key features including a robust 51W power budget, a convenient 12V DC output for external devices, and gigabit-speed networking, this LattePanda IOTA PoE module is the definitive solution for developing reliable, high-performance systems in industrial control, edge computing, and smart surveillance applications.

LattePanda IOTA & 51W PoE Expansion Board

Up to 51W High-Power PoE Supply

This 51W PoE Expansion Board complies with the advanced IEEE 802.3bt standard, providing a maximum power output of 51W. This substantial power budget ensures continuous and stable operation not only for the LattePanda IOTA itself but also for power-hungry peripheral devices such as cameras, sensors, or small actuators. This capability is critical for applications that demand consistent performance and reliability under heavy processing loads, preventing issues like system instability or unexpected reboots caused by insufficient power.

Power + Networking Over a Single Cable – Simplified Wiring

By integrating power and data transmission into one Ethernet cable, this single-cable PoE solution fundamentally streamlines the physical setup of any project. This approach reduces cable clutter, minimizes potential points of failure, and optimizes deployment space. The convenience is especially valuable in compact enclosures or remote installation environments where access to power outlets is limited or impractical. The module maintains a high-speed 1.0 Gbps network connection, ensuring that data throughput is never compromised.

Supports External Device Power Output

A dedicated 12V DC connector is integrated into the Gigabit PoE Hat, allowing it to directly power external components like sensors, cooling fans, or actuators. This feature enhances the LattePanda IOTA's role as a central controller by enabling it to manage and power its entire ecosystem of peripherals from a single source. This expands the system's integration capabilities, making it easier to build self-contained and fully functional solutions without requiring additional power supplies.

Important Notes

• Only the Ethernet port of this Expansion board supports PoE: The built-in Ethernet port on the LattePanda IOTA board does NOT support PoE. Please ensure PoE power is supplied through this expansion board only.
• Use IEEE 802.3bt Compatible Equipment: We recommend using PoE switches or routers that support the IEEE 802.3bt standard. Using lower-specification devices (e.g., 802.3af/at) will result in insufficient power, causing system instability, frequent reboots, or failure to boot.
• Inductor Heating is Normal: The silver inductor on the board (marked “100”) may become slightly warm under light loads due to SSR FPWM mode operation. This is a normal working condition and does not affect performance or product lifespan.
