  • Switchberry is a Raspberry Pi Compute Module 4 carrier that transforms it into a five-port gigabit layer-2 switch.
  • It supports Synchronous Ethernet and Precision Time Protocol (PTP), enabling precision timing with hardware residence-time correction.
  • The device features five RJ45 ports, microSD and microHDMI ports, five SMA connectors for external devices, and optional GPS or Wi-Fi via M.2 slots.
  • Designed for timing-sensitive networks, it can operate as an unmanaged switch, transparent clock, grandmaster, or client in PTP modes.
  • Priced at $999 and currently out-of-stock, its design and software are open-source under a Creative Commons license on GitHub.
