The SparkFun MicroMod STM32 Processor Board high-performance ARM® Cortex®-M4 32-bit RISC core operates at a frequency of up to 168MHz. The core features a floating-point unit (FPU) single precision, supporting all ARM single-precision data-processing instructions and data types. It also implements a complete set of DSP instructions and a memory protection unit (MPU) which enhances application security.
This Processor Board utilizes the DFU bootloader to upload code and incorporates an extensive range of enhanced I/Os and peripherals. To complement the STM32F405 processor, an additional 128Mb (16MB) serial flash memory chip has been added to the underside of the board.
