Looks like this library is not longer available in the index:
https://github.com/arduino/library-registry/blob/main/repositories.txt

Was it removed on purposed? If not, could we re-add it?

The initialize() function always return false. .dataReady() always return false as well, thus no readings can be made. If I try to read the values directly, the arduino seems to just hang.

Does anyone face the same issue?

In the file "src/SparkFun_MAG3110.cpp", in the function "readMag()" there is waiting after the Wire.requestFrom(). This line: while( Wire.available() != 6 ) {} may be removed, it is at the moment at line 93.
Explanation: Common-mistakes#1

Hi @sparkfun,

I'm using this module with an ESP-12 and I'm just running the Basic example. I'm getting very unusual readings. Here is a typical sample:

X: 64895, Y: 425, Z: 64768

What could this be? Have I got a damaged MAG3110? Is there a weird scale value register set somewhere? Any clues would be much appreciated.

EDIT: Upon further investigation - the MAG3110 has two 8-bit registers for each axis. In this library, they're joined and packaged into an int. Shouldn't they be packed into a uint16_t or an unsigned int? Surely there's no sign in the values the magnetometer will spit out. Could I be getting these values due to an overflow?
