The STM32F407ZGT6 is a part of STM32F4 series 32 Bit Microcontroller. It has an storage temperature ranging from - 65 °C to + 150 °C and it is available in LQFP-144 Packaging. The STM32F407 family is based on the high-performance ARM®Cortex™-M4F 32-bit RISC core operating at a frequency of up to 168 MHz. The Cortex-M4F core features a Floating point unit (FPU) single precision which supports all ARM single-precision data-processing instructions and data types. It also implements a full set of DSP instructions and a memory protection unit (MPU) which enhances application security. This simple minimum system board make your development work more easier, it’s cheap but more powerful. By work with it, we can achieve a lot of functions，for example:go with a OTG line for usb host.
