Where is PB11?
Seeing the pin layout I notice that the pin that used to be PB11 in other nucleos is NC
Where is PB11? Is not usable?
or am I just too tired to notice it is somewhere else?

Hi,
Also from user manual here: http://www2.st.com/content/ccc/resource/technical/document/user_manual/98/2e/fa/4b/e0/82/43/b7/DM00105823.pdf/files/DM00105823.pdf/jcr:content/translations/en.DM00105823.pdf From figure 27, I read that this pin is connected to VCAP1: F401RE/F411RE/F446RE/F410RB:VCAP1
So as I understand it, this pin is dedicated to the MCU internal regulator (and cannot be used by application)

From the schematics, PB11 should be pin 20 on CN10. However, the MBED diagram has this pin marked (in error ?) as NC.

Schematics:
Hi, As explained by ST support team, PB11 is not available on the STM32F401RE. Anyway you can find it on the NUCLEO_64 schematics because this NUCLEO 64 platform is the same for every nucleo_64 modules (STM32F030R8 / STM32L476RG / ...) For instance, STM32L476RG has a PB_11 pin connected on pin 20 of CN10 (https://developer.mbed.org/media/uploads/bcostm/xnucleo64_revc_l476rg_mbed_pinout_v2_morpho.png.pagespeed.ic.ktYhk9AHNq.png).
I hope it is clearer for you.
