+| VA2 | Connection for [[pins#Power-over-Ethernet (PoE)|Power-over-Ethernet]]. That is the center tap of the Ethernet coil between RJ45 pins 3 and 6. |
+| VB2 | Connection for [[pins#Power-over-Ethernet (PoE)|Power-over-Ethernet]]. This pin is directly connected to the network jack of Netzer (RJ45 pins 7 and 8). |
+===== Pins of pin header JP2 =====
+^ Name ^ Description ^
+| RST | Use this pin to reset Netzer. The signal is low active (this means 0 resets Netzer). The Reset signal can also be used for waking up Netzer from sleep mode (after shut down). The pin is optional and can be left open.|
+| 3V3 | Pin for power supply. Minimum voltage is 3.1\ V. Maximum voltage is 3.6\ V.|
+| GND | Ground potential.|

+| TX | ::: |
+| RX | ::: |
+| VA1 | Connection for [[pins#Power-over-Ethernet (PoE)|Power-over-Ethernet]]. That is the center tap of the ethernet coil between RJ45 pins 1 and 2. |
+| VB1 | Connection for [[pins#Power-over-Ethernet (PoE)|Power-over-Ethernet]]. This pin is directly connected to the network jack of Netzer (RJ45 pins 4 and 5). |
+===== Power-over-Ethernet (PoE) =====
+The four connections VA1, VA2, VB1 and VB2 are connections from the network socket where a Power-over-Ethernet supply can be connected to.
+{{ :poe.gif?nolink& |PoE example circuit}}
+The image shows an example circuit. Here the PoE supply AG9033 of Silver Telecom is used.
+====== Overview over all GPIO signals ======
+Here only some common informations are shown.
+The implemented functionality of a single IO depends on the single project.
