MicroMod STM32 Processor improves MicroMod applications

SparkFun’s processor board improves MicroMod applications with its Arm® Cortex®-M4 32-bit RISC core

The SparkFun MicroMod STM32 processor board improves MicroMod applications with its Arm Cortex-M4 32-bit RISC core. This little processor board provides an economical and easy-to-use development platform for situations that require more power with minimal working space. With the M.2 MicroMod connector, connecting the STM32 processor is a breeze. Simply match up the key on the processor’s beveled edge connector to the key on the M.2 connector and secure it with a screw (included with all carrier boards). The STM32 is one of the most powerful and economical microcontrollers available, so to be able to add it to MicroMod carrier boards is a huge advantage for any project.

The STM32F405 processor is based on the high-performance Arm Cortex-M4 32-bit RISC core and can operate at a frequency of up to 168 MHz. This core features a floating point unit (FPU) single precision that 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 processor board utilizes the DFU bootloader for uploading code and incorporates an extensive range of enhanced I/Os and peripherals. To complement the STM32F405 processor, SparkFun has also added an additional 128 Mb (16 MB) serial Flash memory chip to the underside of the board.
