=== Introduction ===

[[File:S_PoE_HAT.png | 400px |right]]

ROCK Pi S PoE HAT is a HAT accessories designed for ROCK Pi S. The ROCK Pi S PoE HAT allows you to power your ROCK Pi S 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.

It comes with the following features:

* 802.3af up to 10W(5V/2A)
* Optional 26PIN x2 GPIO pass-through exported
* Works with ROCK Pi S
* Clean design by hiding the the big transformer inside
* EEPROM for HAT identity and driver probe
* headphone jack exported
* Provide 12V power output with 2P connector

=== Supplied with this product ===
* ROCK Pi S PoE HAT
* Mechanical spacers
=== Other hardware needed ===
* ROCK Pi S
* An Ethernet cable
* Power-sourcing equipment for a 802.3af or 802.3at Power over Ethernet network

=== Software support ===

The PoE doesn't require software to power and run.

For the head phone jack and PDM Mic Array support, please update to the latest ROCK Pi S firmware.

==== Usage of Headphone jack ====

* Initialize GPIO0_B7.

The difference between F3 and F4 is, F3 and F4 uses different GPIO for fan control. F4 use ADC for temperature detection, while F3 uses DS18B20.
