This 3D CAD model is a highly detailed rendering of the Raspberry Pi PoE+ HAT (Power over Ethernet Plus Hardware Attached on Top).
1. Functions of the PoE+ HAT
- Power over Ethernet: The PoE HAT is an add-on board that connects to the Raspberry Pi (supporting models 3B+, 4B, and later). This allows the board to simultaneously receive both power and network data over a single Ethernet cable (compliant with the IEEE 802.3at or PoE+ standard).
- Cooling: This model often features a small cooling fan mounted on the HAT to cool the PoE chip and Raspberry Pi during heavy loads.
2. Purpose of the CAD Model
- Enclosure Design: The primary purpose of this model is to provide users with accurate dimensional reference data.
- Assembly Simulation: Engineers and makers can use this CAD file in 3D design programs to:
- Clearance Check: To ensure the HAT fits snugly on the Raspberry Pi and prevents other components from clashing.
- Case Design: To create an enclosure with ventilation holes, fan slots, and Ethernet cable slots that accurately align with the PoE HAT's location.
3. Key components shown in the model
- Standard-sized printed circuit board (PCB) for HAT
- 40-pin GPIO connector for connecting to Raspberry Pi
- Power transformer and PoE power conversion circuit
- Small cooling fan on top
