# RealTimeHAT The RealTimeHAT extends the Gigabit-Ethernet interface of the Raspberry Pi by professional networking functions. Typical applications are **industrial real-time communication** and **network monitoring**. The HAT provides **3 Gigabit-Ethernet ports**, one of which connecting to the Raspberry Pi's Ethernet port. Connection to the Raspberry Pi is realized via the GPIO connector and via a (short) Ethernet cable. Interface SPI0 is for main configuration, using either CE0# or CE1#. Additional information on use cases, programming interfaces etc. can be found on [InnoRoute's website](https://innoroute.com/realtimehat/)., e.g., on using the HAT as an **endpoint in Time-Sensitive Networks**, as a **3-port Ethernet switch**, or to **measure and monitor** every kind of the traffic forwarded through the HAT. To install the necessary software, use the following commands: ```bash git clone https://github.com/InnoRoute/RealtimeHAT cd RealtimeHAT ./install.sh ```
