MSA311 I2C 14-Bit Triaxial Accelerometer Module ±2G–16G
MSA311 Triaxial Accelerometer Module – I2C 14-Bit with Selectable G-Ranges
Upgrade your electronics projects with the MSA311 Triaxial Accelerometer Module — a compact, high-precision I2C sensor board designed for robotics, UAVs, wearables, and embedded systems. Featuring a full 14-bit resolution across three axes (X, Y, Z), this module delivers accurate tilt, motion, and orientation sensing for a wide range of prototyping applications.
Key Features
- 14-Bit Three-Axis Motion Sensing: Captures tilt, movement, and orientation data simultaneously across X, Y, and Z axes for precise motion tracking in your builds.
- Selectable Measurement Ranges: Switch between ±2g, ±4g, ±8g, and ±16g ranges, with data rate options from 1 Hz to 500 Hz — adaptable to vibration monitoring, gesture detection, and more.
- I2C Interface with Clearly Labeled Pads: Board pads labeled VIN, 3Vo, GND, SCL, SDA, and INT simplify wiring to microcontrollers, prototype boards, and development kits.
- Ultra-Compact PCB: Measuring just 2.54 cm × 1.79 cm (approx. 1.00" × 0.70"), this board slots into tight spaces — ideal for UAV flight controllers, robotics chassis, wearable tech, and classroom experiments.
- Broad Compatibility: Works with popular microcontroller platforms and development boards that support I2C communication, including those used in drone and robotics projects.

Frequently Asked Questions
Q: What microcontrollers are compatible with the MSA311 I2C accelerometer module?
A: The MSA311 accelerometer module uses a standard I2C interface, making it compatible with a wide range of microcontrollers and development boards that support I2C communication — including Arduino, Raspberry Pi, ESP32, STM32, and similar platforms commonly used in robotics and embedded electronics projects.
Q: What are the selectable measurement ranges on the MSA311 accelerometer module?
A: The MSA311 module offers four selectable full-scale measurement ranges: ±2g, ±4g, ±8g, and ±16g. You can also configure the output data rate from as low as 1 Hz up to 500 Hz, allowing you to fine-tune the module for applications ranging from slow tilt detection to rapid vibration monitoring.
Q: Does the package include headers, cables, or a microcontroller?
A: No — the package contains only one MSA311 triaxial accelerometer PCB module. Headers, jumper cables, microcontrollers, batteries, and any mounting hardware must be sourced separately.
