NavStik makes used of the cutting-edge 32-bit Cortex M4 processor that runs at up to 168 MHz. It supports full set of DSP instructions and features a Floating Point Unit (FPU) for application that need extremely fast number crunching. Besides these, NavStik comes ready with a huge 1024 kB program memory, and 192 kB of SRAM.
What that means is, if you are still considering using an Arduino or another 8/16 bit processor for your project, think again! NavStik is a few generations ahead of those.
Here is a quick summary of what STM32F4 has to offer:
