From the OCP-TAP & Timebeat team comes the best timing and positioning module for the Raspberry PI CM4!

It's made by the same team who contributed the IEEE1588 capability for the BCM54210PE Ethernet controller in the CM4 to the Linux kernel in collaboration with Raspberry Pi and Broadcom.

This module "sandwiches" in between the IO board and CM4 and has expansion slots to extend functionality and performance at a fraction of the cost of a dedicated timing appliance. 

The Timecard Mini is part of the Timecard ecosystem in production with some of the biggest hyper-scalers in the world today.

The module is currently available with three best-in-class modules from world leader Ublox:

  • LEA-M8F <-- you won't get better performance than this anywhere!
  • LEA-M8S
  • MAX-M10S

All are latest generation products and perform better than any alternative in their class. This is Swiss quality and design clock modules, not Chinese copies.

All modules support all GNSS constellations (GPS, Galileo, GLONASS, Beidou, QZSS and SBAS) in either a single of multi constellation configuration. 

The LEA-M8F supports market leading 100ppb holdover and is the flagship product.

All modules contain a built-in TCXO (temperature compensated oscillator), which allows for short-term holdover, maintaining a level of accuracy to UTC in the event the GPS signal is lost.

The Timebeat CM4 Module clicks into the 100-pin connectors of the CM4 which are easily attached to the CM4 IO board. This is a great solution which leaves the 40-pin connector free on the IO board so you can use it for other project specific functionality.

Once an antenna is connected to the module it can be used to provide a PPS (Pulse per second) to the Raspberry Pi device in addition the NMEA and UBX protocol is available without additional cables to allow advanced configuration and positioning services.

Can be combined with free Timebeat or LinuxPTP software to achieve nanosecond accuracy on the device with IEEE1588 Hardware Timestamping (HWTS).

Both LEA options of the module are capable of disciplining an external oscillator for enhanced stability and holdover capabilities. Timebeat has two modules planned for release in the coming weeks which will hold SiTime MEMS digitally controller OCXO for enterprise-grade holdover taking your Raspberry Pi into the big leagues of timing, competing with kits typically sold for several thousand £££.

These expansion modules click straight into place on the GPS module in expansion slots labeled modules A & B.
