ESP32 Forum

Hey, Im new to using the ESP32 and im having some trouble connecting sensors. Essentially, im trying to connect 2 mpu6050 sensors to an adafruit feather s3. When i have the board plugged into my pc with both sensors connected, it starts continuously connecting and disconnecting. If i unplug one of the sensors then it stops and connects fine. If i unplug the board from the pc and instead power it using a lipo battery, then it runs perfectly. ive previously had this working with no issues, so im not sure why this is suddenly happening. im using arduino ide ad have all relevant usb drivers installed.

Try better quality USB cable.

I’ve tried several cables both usb A to C usb C to C and the same problem persists.

Maybe you just need external pull-up resistors when you have connected 2 I2C devices.
MPU6050 probably have some, but its worth to check.

Also you could post logs, maybe we can see something less obvious.
