MPU-6050/ GY-521 module stopped working

Hi, I know this is like the umpteenth post on this topic, but I have to try.

I have been working to use a MPU-6050 with an Arduino UNO for motion detection. Unfortunately, I have run into the issue of the module no longer being detected with an I2C scanner, on the UNO.

The connections are the typical ones,

  • Arduino | MPU-6050
  • A5 -> SCL
  • A4 -> SDA
  • 3.3V -> VCC
  • GND -> GND

While connecting with jumper wires, the Module was working, but after de-soldering the headers and soldering on wires with the same connection, the module is not being detected with the i2c scanner.

Can the heat of desoldering and soldering easily damage the module or am I doing something wrong?

Any help is much appreciated. Thank you!

very likely problem, has happened to me
Soldering iron = Overheat = Not Working.
happened with a oled display + an adxl345.
U cant do anything bout it

It can be, but is there no way to confirm? Or is the failure to detect in i2c scanner confirmation enough?

yes....we guys were making a project, soldering iron went on i2c display too long and bam, display not working

actually, try as a last resort:-

  1. Heat up joints again and quickly
  2. remove the joints and check the pads

Perhaps the MPU didn't appreciate being connected to 5V SCL/SDA.
I don't know if the MPU is "advertised" as 5V tolerant.
I assume you're using some module thingy.

I shall try that. Thanks!

Yeah, i'm using the GY-521 Module. The module does have an onboard 3.3V LDO. You mean that the UNO analog outputs could be in 5V and thus damage the device?

As far I have seen, most tutorials use the A4, A5 pins directly with the module without any level shifters. But that doesn't guarantee that they are right, ig...

i use mpu6050 always on scl sda without level shifters and they work, have been for 1 year

Well, it just stopped working - "no I2C-scanner presence" stopped. Something to consider.

Maybe both.
Take some close up pictures top and bottom, maybe someone will notice something
