Mag,
Thanks for the feedback! Always helpful to hear the good and the bad of user experience, helps us figure out what to focus on.
1> We’ll get it added to the list.
3> Interesting… I don’t believe I had to do that for mine, but now I want to make sure
4> Thanks! I did the same for my narrow stack housing design, which I put one of our large 1s3p batteries into for very long battery life! We’ll have that housing on the repo soon as well.
5> 3.7v is the only battery voltage I would recommend because it is all I’ve tested, though with the specks on the charger IC, perhaps others would work? I’ve had good results with these two:
- There’s a lot of weird text and icons on the screen that I haven’t been able to understand.*
We are still working on our detailed manual for the Postcard specifically. Much of the iconography is taken from here, though it has been modified for the larger screen size.
- The menu is also very limited: practically all you can do is switch between base and rover mode, and activate the WiFi AP*
We tend to keep the menu’s pretty simple, being able to see information about accuracy and Satellites in View, and swapping around modes. For any in-depth settings changes, a phone or computer is going to be a much better interface than the 5-way joystick.
- The SD card only logs NMEA and not Rinex*
So, if the Postcard is in Base mode, it will log RTCM; RTKLib knows how to turn RTCM into RINEX. I’ve done many successful PPP runs using just the Postcard with stock settings in Base mode.
The Mosaic-x5 is the only unit we sell that has on-device conversion to RINEX, but it is also a much more expensive device with a high complexity. Our idea with the Postcard was to keep things simpler, cheaper, and configurable.
