Sorry for being off-topic. I just want to say, "STM32F405RGT6" is possibly the most hardcore product/model name ever. Just beautiful.

It packs a lot of information in. STM32F4 is ST Micro's range of high-performance ARM Cortex-M4 microcontrollers with FPU, STM32F405 is a particular family of devices in that range differing mainly in package and memory size, R specifies that it's the 64-pin variant, G indicates that it's the version with 1024KB of flash, T is the LQFP package, and 6 is for -40 to 85 °C temperature range. Most of this is shared across the entire STM32 range of devices.

There are usually a dozen variants of the same microcontroller design just with different peripherals, amount of memory, packaging..

You could just as well say STM32 or STM32F4 and that is pretty much 99.9% of the information you need to know :)
