PWM on D9(PC_7)

Does this board have PWM out on D9(PC_7) pin? From the datasheet, it looks like it does and to have a true "Arduino form factor" it should have Pwm on D9(Otherwise its just stupid)

Question relating to:

Affordable and flexible platform to ease prototyping using a STM32F302R8T6 microcontroller.

Ok, I've found this in the user manual: "Warning: PWM is not supported by D9 on STM32F302 since the timer is not available on PC7." Couldn't ST just route another pin? Congrats ST, you just made a board that supports Arduino connectivity withouth the connectivity.

Not certain about this case, but it's not always possible, there are also other platforms from other partners which have similar issues that some pins are used for other peripherals (which might have higher priority for use).

Hello gelecek robotik This is correct that this pin PC7 does not have a PWM on it. You may use another platform from ST that offers you the ability to have PWM on D9. There are plenty of them. The closest from the platform you are using is the NUCLEO-F334R8 https://developer.mbed.org/platforms/ST-Nucleo-F334R8/ Kind regards
