Is it new development board by STMicroelectronics? No mention on st.com, but in System Workbench for STM32 AC6 (openstm32.org) added new choice - STM32F469I-DISCO.
If you will search, you can find image of discovery and price on the digikey.com website too.
The price is $61.25. http://www.digikey.com/
Mouser offers this development board for $84.31. http://mouser.com/
And Farnell ?43.91. http://uk.farnell.com/
You can see that development board contains display with size of PCB, 3 MEMS microphones, minimal 4 LEDs for user control. The board contains holder for microSD card, user USB, jack audio connector and, like STM32F7-disco, only Arduino like connectors.
What really contains? Display looks very nice and, maybe, will be with capacitive touchscreen.
What do you mean? Do you like it?
