5PCS GY-521 6 DOF mpu6050 Accelerometer Sensor Module MPU-6050 3 Axis Gyroscope 3 Axis Acceleration 16 Bit IIC I2C Breakout Board for Arduino

Worked great. Versatile in that they work with Arduino mouse and keyboard libraries. Awesome value for the price!

Taking a course on raspberry pi’s. Have not used them yet but have some ideas for a few of them.

es lo que esperabamos

Really bad quality, the Data keeps drifting.

Good threading, inserted in 3D printing with a hot soldering iron works great but threads need protecting or cleaning afterward. Seems like a lot of awkward sizes included where more of the smaller length and diameter would be useful overall. You'll run out of the small one and have almost useless large one left over. If you can just get one or two sizes in quantity would be better overall.

I am quite impressed with these. If you spin it fast enough it needs to be restarted, here is some Arduino code to do that:const int MPU_addr=0x68; // I2C address of the MPU-6050int16_t AcX,AcY,AcZ,Tmp,GyX,GyY,GyZ;if (AcY==0, AcX==0){ Serial.println("Needs to Reboot"); Wire.beginTransmission(MPU_addr);Wire.write(0x6B); // PWR_MGMT_1 registerWire.write(0); // set to zero (wakes up the MPU-6050)Wire.endTransmission(true); Serial.println("Rebooted");delay(10);}

Tested one with a raspberry pico and the arduino core and I was able to have data graphing in about 30 minutes.I've not used the rest but if they're like the first I'll be very happy.

In my review I will try not to focus too much on the MPU6050 unit itself but rather the board. But as general guidance to other enthusiastic people out there, these low-cost inertial sensors require a lot of de-noising and calibration before being usable for most applications. Overall the noise characteristics of this sensor seem to be stable. (I had almost an identical output during the motion using four units).Some positives:1. Obviously, getting 5 sensors for this price is very good.2. Two different headers are provided with different angles (straight and 90 degrees). This is important if you want to fit your sensors inside a small box.Issues with the board:1. The board is a bit flimsy. So make sure that no unnecessary amount of pressure was used when bolting it down.

You will see many of these on Amz, I got these as they offered good price/unit ratio, and I have spares if I blow them up with my experiments with ESP8266/Arduino.Pretty standard units, they have usable accuracy to 0.01 degrees (I haven't used the accelerate output yet) with an exponential filter applied, but also work well with complementary filters (slow to react) and kalman filter(no good on 8-bit platforms).The gyro is effective in the short term, but will tend to drift over long time periods.Using the I2cdevlib library, you have access to both the raw data, and output from a built-in Digital Motion Processor which allows you to offload complex signal processing of the gyro/accel. from your MCU to the 6050.

The MPU6050 is a great accelerometer to use with the Arduino. This kits at at amazing price includes all you see in the picture and is perfect to interface to the Arduino.You will have to solder the headers to the modules, but that's an easy task.
