Thanks for clarifying.
Can a GPIO pin used to represent event mark? will there be a command to poll GNSS time when the specific pin goes high or low?

Couple of quick technical question about openRTK:

1. the spec sheet talks about 1pps. It, however, does not mention event marks. Does openRTK have a dedicated event mark pin? If not and we have to use GPIO, will the firmware handle time stamps?

2. I noticed the GNSS unit use L1/L2 but not L5. Is L5 available on openRTK as it is stated in the spec sheet?
