The HMC5883L includes state-of-theart, high-resolution HMC118X series magneto-resistive sensors plus an ASIC containing amplification, automatic degaussing strap drivers, offset cancellation, and a 12-bit ADC that enables 1° to 2° compass heading accuracy. The I2C serial bus allows for easy interface.

Me ha costado bastante ver que pasaba porque no funcionaba. Gracias a otros comentarios he canviado la configuracion de HMC5883l a QMC5883L y ya ha funcionado. Uno de los 3 tiene una resistencia smd desoldada como se puede apreciar en la foto

Productos defectuosos que me hicieron perder el tiempo. Sin dirección I2C -> indetectables para el ESP32.El primero me hizo perder el tiempo. Los otros 2 sacados directamente del embalaje no se podía detectar la dirección. El detector I2C en ESP32 funciona perfectamente en otros dispositivos.

As the title says. They are actually QMCs. They still work but a deliberately misleading image/ item title to trick you into thinking they are HMCs

使用するまでにネットで情報を調査する必要があった。GITからライブラリのソースコード（パイソン）をダウンロード＆コンパイルしてどうにか使用することができた。各モジュールの初期データを取るとかなりずれているものがあった。校正しないと使用できないことは確かである。

Worked fine once I determined it was a QMC device. Adafruit's library won't support the QMC. Address: 0x0D
