Frequently Asked Questions
How do I configure the measurement range?
The SPA2032 measurement range is configured through I2C registers. Write to the CTRL_REG4 register to select ±2g, ±4g, ±8g, or ±16g range. Higher ranges are suitable for high-g applications like impact detection, while lower ranges provide better resolution for tilt sensing. Contact BeiLuo FAE team for configuration guidance.
Select range based on expected acceleration levels.
What is relates to SPA2032?
The SPA2032 supports standard digital interfaces (I2C or SPI) for easy integration with microcontrollers. I2C uses 2 wires and supports multiple devices on one bus. sPI provides higher speed with 4 wires. both interfaces are widely supported by MCUs. Contact BeiLuo FAE team for interface design guidance.
I2C for simplicity, SPI for high speed.
What is the power consumption of SPA2032?
The SPA2032 features ultra-low power consumption optimized for battery-powered devices. Active mode current is minimized, and sleep modes reduce power to microamps when not in use. This enables year-long battery life in wearable and IoT devices. Contact BeiLuo FAE team for power optimization.
