A great god teach ah L298N module-CodePudding

Purpose: to use 32 single chip microcomputer control dc motor rotation
Phenomenon: the input 12 v power supply, output 12 v motor, the motor turn not happening outside, but inside you can feel in the rotation, measure the input voltage of 12 v, output is only 0.01-0.30 v between, using delay function to adjust the duty ratio, without too big change,
The great god, take me fly!

Is the load is too big, no-load test voltage between 11.45, but the motor 12 v is written on it!
