OpenIMU300ZA output freezes after 1 minute (approx) when using PPS


Is the PPS signal supported in the firmware as per the documentation?

Output consistently freezes after 1 min when using the INS example App with PPS from the GNSS connected to pin 2.

Many thanks,


Hi Simon,
The PPS function will be ready in next firmware release.

@Li-YiFan thanks for your response.

Do you have a rough estimate of when the next firmware will be released?

Alternatively can you point to to the relevant code in the Beta on github so that I can investigate?



@Li-YiFan Any update on the firmware release?

@simon-rob Hi Simon, the PPS function not support in the old firmware OpenIMU, cuttently we have beta version with PPS on testing, the official firmware/doc will be released in the next few weeks.

@Li-YiFan Quite some time has passed now.. any updates on the next release?
