  • ·Read-only root filesystem option for production

Based on Raspberry Pi OS Lite (Bookworm, 64-bit). Ships with the Timebeat Agent pre-configured and the TimeBeat OTA/OTC device-tree overlays, on a kernel pre-tuned for PTP performance. First boot auto-detects the carrier board and applies the PTP profile defaults, and SSH is enabled out of the box. The Agent handles GNSS, PTP and NTP directly, so no separate gpsd, linuxptp or chrony is required.
