New Original QMC5883L High Precision Three-Axis Magnetometer Sensor Module for IoT/Navigation/Attitude Control instead of HMC5883L

QMC5883L is a high-performance three-axis magnetic sensor launched by a domestic manufacturer. It is based on the third-generation anisotropic magnetoresistive (AMR) technology and is designed for high-precision magnetic field measurement, navigation and attitude detection. With its high precision, low power consumption and small size, QMC5883L has become an ideal magnetic field measurement solution for navigation, Internet of Things and consumer electronic devices.

1. Core features
High-precision measurement:
Resolution: 2 milligauss (mG)/LSB (least significant bit), 16-bit analog-to-digital conversion, and support for ±8 Gauss magnetic field range.
Heading accuracy: 1°~2°, suitable for scenarios such as walking navigation and drone attitude determination.
Low power design:
The operating current is only 75μA, supports a wide voltage range of 2.16V~3.6V, and is compatible with battery-powered devices.
Small size package:
Adopts 3×3×0.9mm³ LGA package, which is suitable for compact design with limited space.
