MMA7361 3-Axis Accelerometer Inclination Sensor Module
MMA7361 3-Axis Accelerometer & Inclination Sensor Module
The MMA7361 Accelerometer Module is a compact, high-performance triaxial acceleration and tilt sensor designed for electronics projects, robotics, and embedded systems development. Whether you're building a motion-sensing device, a tilt-detection circuit, or integrating angle feedback into your microcontroller project, this module delivers precise, reliable readings in a convenient, breadboard-friendly format.
Key Features
- Dual Voltage Support: Compatible with both 5V and 3.3V input — works seamlessly with Arduino, Raspberry Pi, STM32, and other popular development platforms.
- Onboard RT9161 Regulator: Features a lower voltage drop than the standard 1117 regulator with faster load response speed, making it highly suitable for high-noise power supply environments.
- Selectable Measurement Range: The sensing range can be configured via microcontroller IO pin selection or by swapping a resistor, giving you flexibility for your specific application.
- Standard 2.54mm (100mil) Pin Pitch: All commonly used pins are broken out to a standard 2.54mm header, making it perfectly compatible with dot matrix/perfboards and standard jumper wires.
- Triaxial (3-Axis) Sensing: Measures acceleration and tilt across X, Y, and Z axes simultaneously for comprehensive motion and angle data.
- Compact & Easy to Integrate: Small form factor slots neatly into prototype boards, enclosures, and custom PCB designs.

Frequently Asked Questions
Q: What voltage does the MMA7361 Accelerometer Module support?
A: The MMA7361 module supports both 5V and 3.3V input voltages. It features an onboard RT9161 low-dropout regulator, which provides a lower voltage drop than the standard 1117 regulator and offers faster load response — making it an excellent choice for noisy or demanding power supply environments common in microcontroller-based projects.
Q: How do I select the measurement range on the MMA7361 module?
A: The measurement range on this module can be configured in two ways: by toggling a microcontroller IO pin connected to the range-select input, or by swapping the onboard selection resistor. This flexibility lets you tailor the sensitivity of the sensor to suit your specific application, whether you need a wider dynamic range or finer resolution for subtle tilt detection.
Q: Is the MMA7361 module compatible with Arduino and Raspberry Pi?
A: Yes. Thanks to its dual 3.3V/5V compatibility and standard 2.54mm (100mil) pin pitch header, the MMA7361 module works directly with Arduino, Raspberry Pi, STM32, ESP32, and most other popular development boards. All functional pins are broken out, and the standard pitch makes it easy to use with breadboards, dot matrix boards, and dupont jumper wires.
Q: What outputs does the MMA7361 sensor module provide?
A: The MMA7361 provides analog voltage outputs for each of the three axes (X, Y, and Z). These outputs can be read using the ADC (analog-to-digital converter) inputs on your microcontroller to calculate acceleration values, tilt angles, and inclination data in real time.
