QMC5883L with Revo. Wrong magnetometer?
« on: February 20, 2018, 04:10:30 pm »
hi, i've got my magnetometer today and it was labeled as a HMC5883L. but i found the same one on other sites where other people say its actually a QMC5883L, so it seems like i have a QMC5883L. Other sites say its the same magnetometer just made by a chinese factory and that the adress is different.

Is it possible to get a QMC5883L working? the one i got didn't work. I have lent the one from my friend, it has a label with HMC5883L on it and it worked pretty good.

Cloned QMC5883 version is not compatible with HMC5883, need codes changes, not only the I2C address.

Hi アイラ,
I have just ordered one of those new GPS/MAG units with QMC5883L from banggood. I can add support for it as soon as I get it.

Do you think it can be automatically detected?

Most definitely. Pity though that they choose the chip-id register to have value 0xff  :o

I used GY-511 from Banggood, there works fine.
