Another piece of undocumented stuff .. well, from what I read there it should use http://wiki.sunfounder.cc/images/7/72/Q ... et-1.0.pdf as the magnetometer.This is my I2C module which contains compass
Spec of that product says operation Voltage range is 2.16V to 3.6V --> there is either an DC/DC on the product or they toast the 3-axis magnetometer. Ask your seller/manufacturer of that CCC but my wild guess is that the logic levels are 3.3V on I2C interface, 5V for the UART.
An oscilloscope will tell you as my crystal ball is out for repair (lightning strike).
Your MPU6050 should be 3.3V logic level as well (looks like there is an LDO on the board). It may have 2k2 pull-ups assembled. Data sheets are your friends https://invensense.tdk.com/wp-content/u ... sheet1.pdf --> check what is connected to pin23/24.
