Power over Ethernet (I2C_SCL) (I2C_SDA) MoBaCon NETZER NETZER_EXT (I2C_SCL) (I2C_SDA) NETZER Extension MoBaCon This library can be used to easily design Netzer based projects. Netzer R1.1 as package for Netzer based designs
Consists of two 10 pol 2.54 mm pin headers.
Netzer supply and Reset
Netzer is supplied via the 3V3 pin and the GND pin. The voltage should be in between 3.1 V and 3.6 V. Decoupling and buffering capacities are not needed.
Grounding this pin resets Netzer, a short impulse awakes Netzer from sleep (after a shut down). Leave the pin open if not needed. No pullups are required.
Power over Ethernet (PoE, IEEE802.3af)
The Poe-Pins VA1 and VA2 or VB1 and VB2 deliver the PoE-Voltage 48V directly from the Ethernet cable. It depends on the power supply which pairs carry the voltage. Connect a PoE conform DC/DC converter here.
Netzer IO
Here is a short overview over the 13 available pins of Netzer Rev 1.1.
| Netzer Name | PIC Pin | Maximum output current | Maximum input voltage | Description |
| SPI_INT | RC2 | 25 mA | 5.5 V | Interrupt pin of the SPI module (only used in SPI slave mode) - PWM output |
| SPI_CLK | RC3 | 25 mA | 5.5 V | Clock line of the SPI module |
| SPI_MI | RC4 | 25 mA | 5.5 V | Data input of the SPI module |
| SPI_MO | RC5 | 25 mA | 5.5 V | Data output of the SPI module |
| SPI_CS | RF7 | 2 mA | 5.5 V | Select line of the SPI module (only used in SPI slave mode) |
| RX | RC7 | 25 mA | 5.5 V | UART Receive line |
| TX | RC6 | 25 mA | 5.5 V | UART Transmit line |
| IO0 | RB0 | 25 mA | 5.5 V | Interrupt input |
| IO1 | RB1 | 25 mA | 5.5 V | Interrupt input |
| IO2 | RB2 | 25 mA | 5.5 V | Interrupt input |
