Great value. - Works great! Very easy to get going. Just gave the manual to Claude Code or Codex to write the code. Was up and working in a couple of hours on an ESP32-S3. It's very accurate, low power and the form factor is amazing. Will buy again. Review: Have not got it working yet - I have now connected the device to a PC through the 6:1 USB adapter and the Witmotion PC software shows me the attitude of the sensor which is promising. I would now like to use the device with an Arduino MCU board and the Arduino IDE but so far I have not been able to find any suitable Arduino example software. I have found Arduino software for the WT901JY (6 axis version), this does not seem to compile, a library file seems to be missing. If I can eventually get this working I will update this review. ## Features - 【High Precision & High Performance】The acceleration sensor fusion with 9 axis of motion sensing (3-axis accelerometer+3-axis gyroscope+3-axis magnetometer+3-axis Inclinometer+quaternion) & powered by high-performance cortex-M4 core processor, offers real-time and refined measurement data. - 【Why WITMOTION Acceleration Sensors?】The sensor is ideal in various demanding scenarios involving motion sensing in physics and engineering.

Sincerely. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Feature packed inertial platform. Great value. *by J***R on 8 October 2025* Works great! Very easy to get going. Just gave the manual to Claude Code or Codex to write the code. Was up and working in a couple of hours on an ESP32-S3. It's very accurate, low power and the form factor is amazing. Will buy again. ### ⭐⭐ Have not got it working yet *by J***Y on 25 July 2025* I have now connected the device to a PC through the 6:1 USB adapter and the Witmotion PC software shows me the attitude of the sensor which is promising. I would now like to use the device with an Arduino MCU board and the Arduino IDE but so far I have not been able to find any suitable Arduino example software. I have found Arduino software for the WT901JY (6 axis version), this does not seem to compile, a library file seems to be missing. If I can eventually get this working I will update this review. ### ⭐⭐⭐⭐⭐ Ease of use *by M***. on 15 March 2023* Excellent job on how these guys have made such a complicated device so easy to use. There is a lot going on with the fusion algorithms that go into this and having done this myself with all the code that is involved in getting this to work, these guys have removed a lot of the complexity and provided a fairly easy-to-use interface. Very good documentation (assuming you can find it all) and good videos made it fairly straight forward to get it to work OOB (out-of-the-box) and calibrate it. From what I have seen from using competing devices, this by far is the easiest to use and get working - I highly recommend it! Having an I2C and a UART interface is a huge plus - doesn't take long to get it up and running and providing meaningful results. ## Frequently Bought Together - [Arduino Accelerometer Sensor+Inclinometer] WT901 High-Accuracy 3-axis Acceleration+Gyroscope+Tilt Angle +Magnetometer with Kalman Filtering, 9-axis MPU9250 USB 200Hz IMU Raspberry Pi AHRS Module - HiLetgo 3pcs GY-521 MPU-6050 MPU6050 3 Axis Accelerometer Gyroscope Module 6 DOF 6-axis Accelerometer Gyroscope Sensor Module 16 Bit AD Converter Data Output IIC I2C for Arduino - WitMotion USB-UART Converter 3-in-1 Multifunctional Serial Adapter, with CH340 Chip, Compatible with Windows 7/8/10, Linux, Arduino, 300-1.5 Mbps Baud Rates, 12-Month Warranty --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.at/products/313906608-9-axis-imu-module-wt901-mpu9250-module-3-axis-accelerometer](https://www.desertcart.at/products/313906608-9-axis-imu-module-wt901-mpu9250-module-3-axis-accelerometer) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-06-03*
