Customer support was non existent. Well, they responded, but the communication gap was so great, I never received an answer. **Q: Does this unit support external GPS !?** A: No ## Customer Reviews ### ⭐⭐⭐⭐⭐ Ease of use *by on Reviewed in the United States March 15, 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. ### ⭐⭐⭐⭐ Budget Friendly IMU *by on Reviewed in the United States January 4, 2024* I used UART. The software they recommend is very good and almost a must to easily configure the device, with a USB to UART cable. Amazing accuracy for the price, but very difficult to interface with.Their online code samples are not good at all, but you can make your own or find things on github.For Python I would recommend the pywitmotion library on GitHub. All the heavy lifting has been done and its easy to implement. ### ⭐⭐⭐⭐⭐ Very nice module with good software *by on Reviewed in the United States June 12, 2023* The device works very well. Software is easy to use and reports everything with good resolution and fast response time.The support team is also very quick and helpful. I had an issue getting an external GPS to connect but once I set the baud rate (both GPS and module) to 115200 per their suggestion it worked perfectly. They got back to me within an hour with exactly the info I needed.Planning to use this for telemetry on an RC car. Highly recommended! ## 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? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.it/products/88918373-arduino-accelerometer-sensor-inclinometer-wt901-high-accuracy-3-axis-acceleration](https://www.desertcart.it/products/88918373-arduino-accelerometer-sensor-inclinometer-wt901-high-accuracy-3-axis-acceleration) --- *Product available on Desertcart Italy* *Store origin: IT* *Last updated: 2026-06-22*
