Bosch BMA280 3-Axis Accelerometer Sensor, ±16g Range, 14-bit Resolution, Low Power, I²C/SPI, LGA-12 Package
The Bosch BMA280 is a high-precision, low-power 3-axis digital accelerometer in an ultra-compact LGA-12 package. Featuring 14-bit resolution and a programmable range from ±2g to ±16g, it is designed for seamless integration with microcontrollers like Arduino, ESP32, and STM32 via I²C or SPI interfaces, making it ideal for motion, tilt, and vibration detection in space-constrained applications.
Features
- High-precision 3-axis digital accelerometer with 14-bit resolution.
- Programmable full-scale range (±2g, ±4g, ±8g, ±16g) for versatile sensitivity.
- Ultra-low power operation: 130 µA active, 6.5 µA in low-power mode.
- Dual digital interface support: I²C and SPI (3-wire/4-wire).
- Compact 2mm x 2mm LGA-12 package for space-constrained designs.

The Bosch BMA280 accelerometer utilizes a MEMS (Micro-Electro-Mechanical Systems) sensing element to deliver precise measurement of static and dynamic acceleration across three axes. Its high 14-bit digital output ensures fine-grained data for detecting subtle motion, tilt, vibration, and shock events. The sensor operates from a 1.62V to 3.6V supply, making it compatible with both 3.3V and 5V logic systems when appropriate level-shifting is applied.
An integrated intelligent interrupt engine enables advanced, power-efficient motion detection without constant microcontroller polling. Features like tap sensing, orientation recognition, and free-fall detection can be configured via its registers. The built-in 32-sample FIFO buffer allows for data storage, reducing host processor load and enabling efficient batch reading for complex motion analysis algorithms in wearable, IoT, and mobile electronic devices.
