Description

The SparkFun SEN-21325 breakout provides access to the advanced features of the STMicroelectronics LSM6DSV16X MEMS inertial measurement unit. This sensor combines a 3-axis accelerometer and a 3-axis gyroscope, offering configurable full-scale ranges for precise motion tracking in dynamic environments. Its triple-core processing architecture allows for the independent handling of user interface, optical image stabilization, and electronic image stabilization data streams.

Key to its advanced capabilities are the embedded Machine Learning Core (MLC) and Finite State Machine (FSM), which enable on-device pattern recognition and complex motion tracking without burdening the host microcontroller. The inclusion of a Qvar (capacitive sensing) channel further expands its utility for touch and gesture detection. The board operates from a 1.71V to 3.6V supply, making it suitable for low-voltage logic systems.

Key Features

STMicroelectronics LSM6DSV16X 6DoF IMU (3-axis accelerometer + 3-axis gyroscope).
Wide, user-selectable measurement ranges: Accelerometer (±2/±4/±8/±16 g) and Gyroscope (±125 to ±4000 dps).
On-board Machine Learning Core (MLC) for edge AI and pattern classification.
Integrated Finite State Machine (FSM) and Qvar capacitive sensing channel.
Supports I2C, SPI, and MIPI I3C v1.1 communication protocols.
Dual Qwiic connectors enable solderless daisy-chaining in I2C ecosystems.
Standard 0.1" header pins provided for direct soldering and custom wiring.
Ultra-low power consumption with dedicated always-on and wake-up functions.

Applications

Advanced robotics and drone stabilization systems requiring high-rate inertial data.
Wearable devices and smart watches for activity tracking and gesture recognition.

Frequently Asked Questions

What is the operating voltage range for this IMU breakout board?

The LSM6DSV16X IC on this breakout requires a supply voltage (Vdd) between 1.71V and 3.6V. The I/O voltage (Vddio) can be set independently from 1.08V to 3.6V, allowing flexible interfacing with 1.8V, 3.0V, or 3.3V logic microcontrollers.

How do I connect this board using the Qwiic system versus the header pins?

For quick prototyping, use a Qwiic cable to connect the board's two Qwiic ports to any other Qwiic device or adapter in a solderless daisy-chain. For permanent installations or custom wiring, solder headers to the 0.1" pitch breakout pins to access the I2C, SPI, power, and interrupt lines directly.

What is the purpose of the Machine Learning Core (MLC) and Finite State Machine (FSM)?

The embedded MLC allows you to run trained machine learning models directly on the IMU to classify motion patterns (like gestures or activities) without host MCU intervention. The FSM can be programmed to detect specific motion sequences or thresholds, triggering interrupts. Both features significantly reduce system power consumption and processing load.

Can I use this sensor with both 3.3V and 5V Arduino boards?

The sensor IC itself is not 5V tolerant. When connecting to a 5V Arduino (like Uno), you must use a logic level converter for the I2C or SPI lines. Power to the board's VCC must be regulated to 3.3V. For 3.3V boards (like 3.3V Arduino variants, ESP32, or Raspberry Pi), you can connect directly.
