Generic (unbranded)
GY-521 is the generic MPU-6050 breakout most Arduino kits ship: 3-axis accelerometer (±2/4/8/16 g) and gyroscope (±250–2000 °/s) with on-chip DMP, I2C at 0x68 (0x69 with AD0 high, 4.7 kΩ pull-down), onboard 3.3 V regulator, 8 pins incl. XDA/XCL auxiliary I2C and INT, 21 × 16 mm PCB, about $4.

Guidance to help you shortlist. The basis is shown for each recommendation.
6-axis MPU-6050: accelerometer ±2–16 g and gyroscope ±250–2000 °/s over I2C, with DMP; ProtoSupplies names self-balancing robots and gesture recognition as uses.
Engineering inferenceNo-load speed, rated performance and stall limits describe different operating points. A stall specification is not a continuous operating rating.

Ranges are the largest selectable full-scale setting; noise densities are typical datasheet values.
No-load, rated-load and stall figures retain their separate test conditions.
Stall torque and current are not continuous ratings. Check the duty cycle and starting load when choosing the driver and power supply.
Product operating conditions, chip ambient ratings, package case limits and junction maxima remain separate.
Reported product dimensions may exclude protruding components. Unknown height does not establish a complete clearance envelope.
Attached generated geometry is an approximate envelope. A generated outline does not establish an electrically verified PCB footprint.
