Hi seulater,
The #s on the homepage are the total chip capacity. The code space and available RAM specs are what is left for your code.
Effectively, the networking stack and .NET Micro Framework runtime take some of the flash and RAM.
For your code, you have 384KB of flash and 100KB+ of RAM.
This is similar to buying a new tablet or phone; for example, a 16GB phone may only have 11GB of free space.
We try to always quote the _available_ space in descriptions, in specs, etc. But we wanted to make sure people knew we were using the 1MB flash STM32F4 chip in the front page banner.

I thought that's what it was, Thanks for the confirmation.
