Hi
I am working on a custom PCB board featuring a stm32 and a H-bridge to drive a DC motor. I am facing some noise only when i pwm (16KHz). I can also measure the noise on the other pins of the MCU. I have added a scope picture and the circuit. Any comments is very appreciated!
I found out the caps C3 and C4 made a lot of instability, so they are NOT mounted.
Friendly regards, David
