I'm using MPU6050 Accelerometer+Gyroscope and 433 MHz RF RX/TX module for a project with Arduino
UNO. I'm calculating roll-pitch-yaw angles both of accel and gyro. And I used complementary filter to obtain smoother results. So, I send the data with 433 MHz RF. I'm doing calculations on transmitter part.
But, I have a problem. I constructed the circuits and I run them successfully when I feed the transmitter part from serial port of computer. But when I used a battery instead of a USB cable, It dosen't send any data.
I'm using 3.7 Volt, 500 mAh, 9 Wh two battery in series.
Thanks. It's solved. It's caused by battery as I think. MPU6050+433RF+long program code comes heavy for 500mAh battery. I got some powerfull battery, as 1.7 Ah, then it works great!
hallo, i also connect the mpu6050 with the battery which provide 3v,and mpu6050 connect with arduino uno board, except the pin 3.3v was took off and the other pins are connected wiht SDA SCL INT. But i run the code in the arduino it doesn't work,do you know the reason? In the datasheet it says mpu6050 can work from 2.4v to 3.4v
You'll see that not only the power voltage needs to be 3.3V but also I2c signal lines need shifting between 3.3 and 5V
Notice there are lots of 6050 boards available some of them doing that shifting some of them not.
Unless you don't specify clearly what board you have, how did you connected it, you-ll not get an answer since no one here is telepathic to read remotely into your brains.

Normally a 0.5Ah LiPo wouldn't have the slightest difficulty sourcing larger currents that those devices
need, so I wonder why it was an issue. I'd expect 0.5A to 15A depending on the specific kind (1C to 30C).
Hello !! Greetings of the day.
I am working on a project based on MPU6050+RF module. I am having few issues with Transmitter and Receiver codes. Can you please help me out with code.
