Generic 1B26A GY-271 HMC5883L 3-Axis Magnetic Electronic Compass Module

Product description

Description: QMC5883L is a multi-chip 3-axis magnetic sensor compatible with HMC5883L.

Targeted for high precision applications such as compassing, navigation in drone, robot, mobile and hobby purpose applications.

This triple axis compass magnetometer sensor module with power supply of 3.3V or 5V.

The module size is: 16mm*18mm.

There is a 2.54mm pin pitch.

It comes with a pin header.
