MMA6900KQR2

MMA6900KQR2 is a 3‑axis MEMS accelerometer from the MMA family (NXP/Freescale) with a digital output interface (I2C/SPI). It’s designed for low power motion sensing and compact integration in mobile devices, wearables, and automotive applications. The device provides configurable measurement ranges, high-resolution data, and features suitable for tilt/orientation detection, activity monitoring, and vibration sensing. The KQR2 suffix identifies the specific package/grade variant; exact pinout, electrical specs, sampling rate, and full‑scale range are in the official datasheet. In short, it’s a small, low‑power, digitally interfaced accelerometer ideal for embedded motion sensing—verify details in the datasheet for your design.
