SparkFun MicroMod STM32WB5MMG Processor

The SparkFun MicroMod STM32WB5MMG Processor is a remarkable addition to the MicroMod ST product line, offering a potent blend of computing and wireless capabilities in one M.2-connectable processor. This ultra-low power microcontroller from STMicroelectronics™ utilizes a pair of Arm® Cortex® processors: a Cortex-M4 for primary computing, and a Cortex-M0 for running the 2.4 GHz RF stack. The module's radio is certified for Bluetooth® Low Energy 5.3, Zigbee® 3.0, and OpenThread.

The Cortex-M4 CPU operates at a frequency of up to 64 MHz and 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. The processor also includes an additional 128Mb (16MB) serial flash memory chip, making it ideal for a variety of applications.

Sparkfun's MicroMod ecosystem is a modular interface that connects a microcontroller “processor board” to various “carrier board” peripherals. Using the M.2 standard, the MicroMod standard allows for easy swapping of processors. Simply pair a specialized carrier board for the project you need with your choice of compatible processor!

The STM32WB5MMG Processor is equipped with an integrated chip antenna for the RF stack, with a Tx output power of up to +6 dBm and Rx sensitivity of -96 dBm for BLE and -100 dBm for 802.15.4 protocols. This makes it an excellent choice for projects requiring robust wireless connectivity.

Other notable features of the STM32WB5MMG Processor include two UART (one low power), two I²C Buses, SPI, I2S Audio, 16-bit Advanced Four-Channel Timer, two Dedicated Analog Inputs, two Dedicated PWM, and eight General Purpose I/O Pins. This wide range of features allows the processor to be highly adaptable to various project requirements.

Overall, the SparkFun MicroMod STM32WB5MMG Processor is a versatile and powerful tool for any project requiring a compact, wireless-capable microcontroller. Its wide range of features and capabilities make it a standout choice in the world of microcontrollers.
