Nucleo board requirements question

Ok so I see that the latest Pin2dmd solution uses an STM32F429 nucleo-144 development board. This board seems like it has capabilities that are unused by pin2dmd projects(lcd screen connector, Ethernet port) and it has an integral st-link. I’m wondering if there’s a simpler board(cheaper) that has the proper capability and also if a version exists without the st-link built in as the st link is only needed for initial programming and can be snapped off and reconnected via jumpers later if needed. I’m not super familiar with these micro controllers and capabilities/compatibility. Thoughts?

Only the STM32F429 is sucessfully tested. Other F4 and L4 are to slow from the cpu clock side.

F7 and H7 use a different architecture and are not code compatible due to the use of HAL instead of StandardPeripheral library. 

I have already started to port the code to HAL and the basic things are working on a H7 (display output, pinball input, sd card, usb etc)
but still a long way to go and by far not prio 1 on my todo list.
