BMA530

The BMA530 is a 3‑axis MEMS accelerometer from Bosch Sensortec. It provides digital output (I2C or SPI) and is designed for ultra‑low‑power motion sensing in wearables, smartphones, and IoT devices. Key features typically include programmable full‑scale ranges, multiple data rates, low‑noise acceleration measurements, and several power modes (including sleep/low power). It also offers interrupt outputs for motion/activity events and a self‑test function for quality checks. The device is offered in a compact LGA package and integrates well with Bosch’s development tools and documentation. Common applications include activity tracking, gesture or orientation sensing, and general inertial sensing in mobile and wearable devices. In short, BMA530 combines low power, compact size, and reliable Bosch MEMS technology for versatile motion sensing.

Equivalent products to the Bosch BMA530 include: Bosch BMA400 (closest), BMA280/BMA250; STMicroelectronics LIS3DH and LIS2DH12; Analog Devices ADXL345 and ADXL362; Kionix KX022/KX132; and TDK/InvenSense ICM-206xx IMU series. Choose by power consumption, noise performance, embedded features (step counter/FIFO), and interface.

The BMA530 is supplied in a 12-pin LGA package. Key pin functions (typical) are:
- Power/Ground: VDD (power), VDD_IO (IO supply), GND
- Digital interfaces: I2C (SDA, SCL) and SPI (SCK, MOSI/SDI, MISO/SDO, CS)
- Interrupts / signals: INT1, INT2 (programmable interrupt outputs)
- Additional pins: N.C. / reserved for factory/test use
