Présentation

Description

The MPU-6050 (often seen as MPU-6050A in listings) is a 6‑axis MEMS IMU: a 3‑axis accelerometer and a 3‑axis gyroscope, with an on‑chip Digital Motion Processor (DMP) for motion estimation.
Key points
- Interfaces: I2C (SCL/SDA); I2C address 0x68 or 0x69 (depending on AD0).
- Outputs: 16‑bit raw accelerometer and gyroscope data; built‑in temperature sensor.
- Ranges: accelerometer ±2/4/8/16 g; gyroscope ±250/500/1000/2000 deg/s.
- Data rate: can output data up to about 1 kHz (with configurable sample rate and low‑pass filter).
- Features: optional DMP for quaternion/Euler orientation, gesture detection; interrupt output.
- Power: low power operation; simple wake‑up sequence (PWR_MGMT_1).
- Applications: drones, robotics, wearables, motion tracking.
- Notes: Some libraries rely on the DMP; many developers read raw data and fuse externally. No magnetometer.
If you’re seeing MPU-6050A, it’s usually just a variant/name for the MPU-6050.

Pinout

The MPU-6050A is supplied in a 24-pin LGA package (4 × 4 mm). Key pin count/functions:
- Power/Ground: VDD (core/analog supply), VLOGIC/VDDIO (I/O supply), GND.
- I2C interface: SDA (data), SCL (clock), AD0/ADO (I2C address select).
- Interrupt/sync: INT (interrupt output), FSYNC (frame sync input).
- Auxiliary I2C master: XDA, XCL (auxiliary data/clock to connect an external magnetometer).
- Other: multiple NC/reserved pads and thermal/ground pad for PCB mounting.
Functionally the device contains a 3-axis accelerometer and 3-axis gyroscope with on-chip 16-bit ADCs, digital motion processor (DMP) firmware support, configurable full-scale ranges and filters, and communicates digitally over I2C (no analog outputs).

Manufacturer

- Manufacturer: InvenSense (now part of TDK Corporation).
