+The Switchberry V1 is an OCP-TAP open source hardware project to build an open 1 Gbps managed Ethernet switch with PTP capabilities:
+
+> The PCB integrates a managed 7-port Gigabit Ethernet switch, exposing various interfaces and peripherals for a versatile and cost-effective 1G network switch with precision time protocol (PTP) capabilities.
+
+At its heart is a [Microchip KSZ9567STXI](https://www.microchip.com/en-us/product/ksz9567) 7-port Gigabit Ethernet switch with IEEE 1588, SGMII/RGMII/MII/RMII.
