Can confirm. I stripped down my 450 quad to the power delivery system and planted a Here4 with FC firmware in place of the Cube orange+. Loaded in the appropriate parameters from the Cube, set up the gyros and accels, did a compass swing and a short very careful flight. It flew exactly like it did with the Cube although I didn’t fly very long or far and don’t intend to. I’m thinking it’s home might be on a rover.
Please keep in mind that the Here has one IMU that is not isolated and it only has one serial port that also is used for GCS access and two CAN ports. Very limited for possible peripherals and not intended for airborne craft. It was a fun experiment but I will likely flash it back to peripheral status. Cheers😎
