Good afternoon,

One of our customers is using a HERE3 GPS unit with their Cubepilot and I’ve been looking for a schematic for this device to no avail. We are trying to ascertain whether the device will output NMEA directly using a UART, and if so, which pins/header does this come out on? I understand this device uses a uBlox NEO-M8P and the documentation seems to suggest this chip does indeed at least have a UART but I am currently unsure whether these pins are connected and whether it’s enabled(it appears pin 2 needs either grounding or otherwise to enable it).

Any help would be gratefully received.

There is no uart output on Here3. He needs to translate the signal from UAVCAN.  
Alternate method is using the Cube as passthrough
