Hi.
I did a flight today with the third compass RM3100. Earlier I wrote in the post about the strangely low frequency of samples during non-flying testing. After 4 minutes of flight RM3100 looks as if the range has changed … In addition, the z axis seems to have died … After the flight when testing RM3100 the readings are normal. I have several sensors on the I2
I bought on aliexpress. I just had to solder the z axis coil because it was soldered in reverse. In addition, I put a 3.3v stabilizer from 5 and a power blocking capacitor. I shorted the spi / i2c and CS lines at + 3.3v. The compass calibrates well, but there are some problems. I wonder if it is not with the driver …
