=== Gigabit Ethernet ===
On-board Ethernet PHY (Micrel KSZ9031RNX) provides interface signals required to implement the 10/100/1000 Mbps Ethernet port. The transceiver is connected to the Gigabit Ethernet Controller (GEM) through RGMII interface on MIO bank 1, pins PS_MIO[16:27]. For further details (eg: connection and selection of the magnetics), please refer to the Micrel KSZ9031RNX datasheet. The following table describes the interface signals:

=== USB ===
BORA Lite provides one USB 2.0 (Full Speed, up to 480 Mbps) port with on-board PHY (SMSC USB3317) and support to the On-The-Go (OTG) specifications. The transceiver is connected to the USB1 controller (MIO bank 1, pins PS_MIO[28:39]). The following table describes the interface signals:

=== Quad-SPI ===
Quad-SPI is used to access multi-bit serial flash memory devices for high throughput and low pin count applications. The controller operates in one of three modes: I/O mode, linear addressing mode, and legacy SPI mode. The following table describes the interface signals:

<section end=SPI/><section begin=I2C0/>
=== I²C0 ===
This I²C module is a bus controller that can function as a master or a slave in a multi-master design. It supports an extremely wide clock frequency range up to 400 Kb/s. I²C0 is internally connected to the following devices:

<section end=SDIO/><section begin=UART1/>
=== UART1 ===
The UART controller is a full-duplex asynchronous receiver and transmitter that supports a wide range of programmable baud rates and I/O signal formats. UART1 port is routed to the SOM connectors as a 2-wire interface. The following table describes the interface signals:
