Add motion sensing, tilt detection, and vibration analysis to any project with this AX22-sized board. A proven InvenSense MPU-6050 (3-axis accelerometer + 3-axis gyroscope) sits on a 22 × 22 mm PCB, buffered by a 3 V LDO and bidirectional level shifters so any 1.8 V, 3.3 V, or 5 V microcontroller can talk I²C straight away. The chip’s built-in Digital Motion Processor (DMP) can fuse accel-gyro data internally, off-loading costly math from your MCU, while an optional interrupt line lets you wake on motion or FIFO thresholds. Drop it into any AX22 backplane and you’re logging angles, steps, or vibrations in minutes with Arduino IDE, MicroPython, or MicroBlocks.
