Welcome @MohanRaj, to the community!
The STM32F4DISCOVERY is based on an STM32F407VGT6 in an LQFP100 packaging. The same STM32F407 is also available as:
where you automatically have more GPIOs and the rest remains identical. However, you would have to develop your own board for this, as there is not a DISCOVERY or NUCLEO board for each of the 4000 different derivatives of STM32.
Does it help?
Good luck!
