Fix: Check that pull-up resistors (4.7k) are present on SDA and SCL in your schematic. The UPD model often includes them internally, but some versions require external. isis proteus model library gy 521 mpu6050l upd exclusive
The ISIS Proteus model library for the GY-521 MPU6050L provides a virtual representation of the module, allowing users to simulate its behavior in various circuit designs. The library includes: Guide: MPU6050 (GY-521) with ISIS Proteus & Hardware 1
