What is the Open Timecard Mini?

  • Compact PTP & NTP Grandmaster Clock

    Unlike traditional IEEE-1588 PTP grandmaster clocks, Timebeat's Open Timecard Mini 2.0 is available in a range of form factors. From simple modules and plug & play PCIe Cards through to table top appliances brimming with advanced technology

  • Provide clock sync to nanoseconds

    Achieving rock solid single digit nanosecond event timestamping and synchronisation. Complimented by Timebeat software, mitigating the network jitter and clock drift usually experienced in high throughput environments.

  • Budget Friendly & Built for scale

    Engineered to reflect the high fidelity performance of our Flagship Open Timecard, stripped back to be as cost effective as possible and without compromising on performance.

Why Open Timecard Mini?

Small form factor

The 11.5cm x 7cm PCIe IO form factor makes it easy to integrate into your existing device such as PCs or servers, simplifying your workspace. Available with both half-height and full-height bracket.

Various solutions tailored to your needs

4 New Sandwich boards, each with their own unique performance specs. Each capable of operating with all standard CM4 Base boards or compatible products.


From high-precision timing for PTP/NTP Grandmaster clock solutions, to high-precision location services for Industrial IoT and Automotive. The new mini 2.0 range has what you need.

Raspberry Pi CM4 compatible

Our PCIe cards take complete advantage of all the CM4 IO board features with the 40Pin GPIO available, 2 USB-C ports, microHDMI port eMMC boot port and a USB-A port.

And our modules are CM4 pin compatible so work with other 3rd party base boards or even CM4 compatible clones.
