SparkFun MicroMod STM32 Processor Board

SparkFun Electronics MicroMod STM32 Processor Board features an ARM^® Cortex^®-M4 32-bit RISC core in an economical and easy-to-use development platform. The compact Processor Board offers an M.2 MicroMod connector allowing easy connection to a processor’s beveled edge connector with a screw (included).

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.
