Regarding STM32 boards based on register and GPIO pins

[MohanRaj]

 Hi,

I am working in STM32F4 Discovery, in my project I want more GPIO pins but with Same registers so that  I can straight away copy  the  old programs and do programming, Is there any suggestion Please do let me know.

Thanks,

Mohan

Welcome @MohanRaj, to the community!

The STM32F4DISCOVERY is based on an STM32F407VGT6 in an LQFP100 packaging. The same STM32F407 is also available as:

• STM32F407ZGT6 (LQFP144)
• STM32F407IGT6 (LQFP176)
• STM32F407IGH6 (UFBGA176)

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!
