Making USB OTG work with the Blackpill V3.0 board #24

Hi, I have a v3.0 blackpill board with a F401CEU chip. I am not certain if it is possible to implement a portable USB host with this board; it would need external power and I would like to use the USB-C connector to connect self-powered devices to it. Is that possible and if yes do you have some information on how I would have to set up VBUS and power for the board, and if I need any external parts apart from the blackpill board itself?

Thanks a lot.

Did a little bit of reading; does the blackpill board have a charge pump installed on the board?
