STM32 family of 32-bit microprocessors and 32-bit microcontrollers are some of the most popular platform chipsets in use today. They are based on an Arm processor. These Arm® Cortex®-M processors have been designed to offer a great deal of flexibility to computer on a chip (CoC) users. They offer a wide selection of products that combine high performance, real-time capabilities, digital signal processing, low-power / low-voltage operation & connectivity in a easy adaptable and configurable design. The STM32 development board comes with a large selection of tools and software to support any project development large or small. The most popular product commonly used is a 32.768 kHz tuning fork or a watch crystal. Below is a list of ST Micro approved products from ECS Inc.
