Radxa 23W PoE HAT
Radxa 23W PoE HAT is a HAT accessory designed for Raspberry Pi, Radxa ROCK 3 and 4 series, and Jetson Nano.
The 23W PoE HAT allows you to power your Raspberry Pi, ROCK 3 and 4 series or Jetson Nano using Power over Ethernet–enabled networks;
for this product to be used, the network it is connected to needs to have power-sourcing equipment installed.
Hardware Introduction
Supported Products
| Model | Supported Products |
|---|---|
| F3 | Raspberry Pi 3B+, Raspberry Pi 4, ROCK Pi X, ROCK 3A, ROCK 3C, ROCK 4C+, Jetson Nano |
| F3L | F3 with 40PIN GPIO pass-through exported |
| F4 | ROCK Pi 4A / 4B / 4A+ / 4B+ / 4SE |
| F4L | F4 with 40PIN GPIO pass-through exported |
The difference between F3 and F4 are:
F3 and F4 use different GPIO for fan control. F4 uses ADC for temperature detection, while F3 uses DS18B20.
F3 and F4 use different PoE pins. As the picture following:
The difference between Fx and FxL:
FxL has the 40 pins GPIO pin-out, you can also use the 40 pins GPIO, but you can't while using Fx. As the picture following:
Features
- 802.3at up to 23W(5V/4.6A)
- PWM control FAN up to 12000RPM
- Temperature sensor DS18B20
- Optional 40PIN GPIO pass-through exported
- Compatible with Radxa ROCK, Raspberry Pi 3B+ and Raspberry Pi 4
- Clean design by hiding the fan and the big transformer inside
- EEPROM for HAT identity and driver probe
