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)

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.
