概述

Description

MPU-6050 (often seen as MPU-6050A in some catalogs) is a 6‑axis MEMS inertial measurement unit: 3‑axis accelerometer and 3‑axis gyroscope, with an on‑chip Digital Motion Processor (DMP) for sensor fusion and quaternion outputs. It also includes a temperature sensor. It communicates over I2C (default address 0x68, 0x69 if AD0 is high) and runs from 2.375–3.46 V.
Key specs:
- Accelerometer: ±2/4/8/16 g
- Gyroscope: ±250/500/1000/2000 °/s
- FIFO buffer and optional DMP for reduced CPU load
- Interrupts for data-ready events
Common uses:
- Motion sensing for Arduino/ESP32/RPi projects
- Drones, robotics, wearables, gesture control
Notes:
- The “A” suffix isn’t official; if you meant MPU-6050, the above applies. Check the exact part number if sourcing (some vendors use variants like MPU-6050A).

Features

Key features of MPU-6050A (6‑axis MEMS):
- 3-axis accelerometer and 3-axis gyroscope (6-axis) with 16‑bit outputs
- Built-in Digital Motion Processor (DMP) for motion calculations (quaternions, gravity, linear acceleration)
- Internal temperature sensor
- Digital I2C interface (SCL/SDA); I2C address selectable (0x68 or 0x69)
- Programmable full-scale ranges: accelerometer ±2/4/8/16 g; gyroscope ±250/500/1000/2000 °/s
- Digital Low Pass Filter (DLPF) with configurable bandwidth; configurable sample rate
- FIFO buffer (for streaming data) and interrupt outputs (data ready, motion, FIFO overflow)
- Power management: low power modes, sleep/standby; supply voltage typically 2.0–3.6 V
- Small package suitable for compact devices and wearables
(Note: no magnetometer; primarily a motion sensor with onboard processing to reduce host CPU load.)

Package

MPU-6050A uses a 24‑pin QFN (4×4 mm) surface-mount package.

Pinout

Pin count: 24 pins (24‑pin package).
Function: MPU-6050A is a MEMS 6‑DOF IMU (3‑axis accelerometer + 3‑axis gyroscope) with an internal digital motion processor (DMP). It communicates via I2C (SCL/SDA) with a selectable I2C address via AD0. It also provides an auxiliary I2C bus (XDA/XCL) for external sensors or I2C master operations, plus FSYNC input and INT interrupt output. Power/GND pins supply the device (typical operation around 3.3V).

Manufacturer

MPU-6050A is manufactured by InvenSense, a fabless semiconductor company that designs MEMS inertial sensors (accelerometer + gyroscope). InvenSense was acquired by TDK Corporation and now operates as a subsidiary of TDK.

Application

Applications of MPU-6050A (6-axis IMU: accelerometer + gyroscope):
- Consumer electronics: orientation and motion sensing
- Drones/RC: attitude estimation and stabilization
- Robotics: pose tracking and control
- Wearables: activity monitoring
- VR/AR: head tracking and gesture control
- Industrial: vibration monitoring
- Camera stabilization and gimbals

Equivalent

Equivalent 6-axis IMU options to MPU-6050A (gyro + accel):
- InvenSense MPU-6500
- InvenSense MPU-9250 (adds magnetometer; 9-axis)
- InvenSense ICM-20602
- STMicroelectronics LSM6DS3
- Bosch BMI160
Note: these are I2C/SPI MEMS IMUs with similar capabilities; choose based on package, power, noise, and availability.
