- Supports the IEEE 802.3af/at standard (PoE/PoE+).
- Uses a fully isolated switch-mode power supply (SMPS).
- Onboard USB Type A socket can supply up to 5 V / 4 A MAX to external devices.
- A 12 V output is available via a pin header, rated at 2 A maximum.
- Includes an onboard active cooling fan for improved heat dissipation.
- Product size: 56.5 × 65 mm.
- The USB Type A port is for power delivery only – it does not provide data communication.
Notes and version constraints
- The source contains placeholders and incomplete sections (e.g., {{{name2}}}, {{{userDefinedInfo}}), so some details such as exact connector dimensions or additional specifications are missing.
- No explicit commands or configuration instructions are present in the source; if software configuration is required, it must be documented separately.
- Compatibility with Raspberry Pi models other than 3B+/4B is not stated and should be verified before purchase.
- The maximum power consumption of external devices connected to the USB port depends on the available PoE input power; this information is not provided in the source.
