Postcard RTK: Is it possible to add IMU 19?

Hi everyone.
Hi @sparky and @PaulZC
Is it possible to add an IMU19 to the Postcard RTK with the portability protector?
That would be great.

Hi Angel (@amlago ),

It is difficult… I have thought about it, but there is no easy way to connect up the UARTs.

The IM19 needs to be fed with NMEA GGA+GST+RMC at 5Hz. We could do that with the LG290P UART3.

It needs PPS too. We have access to the LG290P PPS signal.

But we also need to connect the IM19 to an ESP32 UART, so we can: configure the IM19, and receive the GPFMI NAVI messages containing the compensated position. There is no easy way to do that on Postcard. Or, at least, I can not think of one…!

(We do have new RTK products in the pipeline which include the IM19 for tilt compensation. But they are still in development… :wink: )

Best wishes,
Paul

Thanks, Paul. It was an idea.
There was a possibility it could be easy. Ja ja.
