GY-9250 9-Axis Motion Sensor Module (I2C/SPI) – Refurbished Chip (No Magnetometer Function)

Description

Product Overview

The GY-9250 9-Axis Motion Sensor Module is a high-performance motion tracking board based on the InvenSense MPU-9250 sensor. This module integrates a 3-axis gyroscope, a 3-axis accelerometer, and a Digital Motion Processor (DMP) for complex motion processing .

Important Note: This is a refurbished unit. The magnetometer function is not operational on this module. You will only have access to 6-axis motion data (gyroscope + accelerometer), not the full 9-axis functionality .

The module communicates via I2C or SPI interfaces, giving you flexibility in connecting to your microcontroller. It is equipped with an onboard 3.3V voltage regulator and logic level converters, allowing direct connection to both 3.3V and 5V systems like Arduino, ESP32, ESP8266, Raspberry Pi, and STM32 .

The MPU-9250 is a multi-chip module (MCM) that contains two dies in a single QFN package: a 3-axis gyroscope, a 3-axis accelerometer, and a 3-axis magnetometer – though the magnetometer on this specific unit is non-functional. The DMP (Digital Motion Processor) can offload motion processing tasks from your main microcontroller, enabling complex orientation tracking with minimal CPU load .

Whether you are building a drone flight controller, a self-balancing robot, a VR headset, or any application requiring motion sensing, this refurbished GY-9250 module offers a cost-effective solution for 6-axis motion tracking.

Key Features

• 9-Axis Sensor (Magnetometer Non-Functional): Based on MPU-9250 with 3-axis gyroscope, 3-axis accelerometer, and Digital Motion Processor (DMP). The magnetometer is not operational on this refurbished unit .

• Digital Motion Processor (DMP): Onboard processor can perform complex motion processing (sensor fusion) independently, reducing load on your main microcontroller .

• Dual Communication Interfaces: Supports both I2C (up to 400 kHz) and SPI (up to 1 MHz) protocols for flexible microcontroller integration .

• Onboard 3.3V Regulator & Level Shifter: Accepts 3V–5V power input and includes logic level conversion, making it directly compatible with both 3.3V and 5V systems .

• 16‑bit ADC Output: Built-in 16-bit analog-to-digital converters provide high-resolution data output for gyroscope and accelerometer .

• Selectable Measurement Ranges: Gyroscope: ±250, ±500, ±1000, ±2000 dps; Accelerometer: ±2g, ±4g, ±8g, ±16g .

• Built-in Filters: Onboard filters reduce noise from motors and other high-current electronics, ensuring cleaner readings .

• Onboard Pull-up/Down Resistors: Includes pull-up resistors on SDA, SCL, and nCS lines, and pull-down resistors on FSYNC and AD0 for simplified wiring .

• Power Indicator LED: Visual confirmation when the module is powered .

• Immersion Gold PCB: High-quality PCB with gold-plated pads for better solderability and corrosion resistance .
