Microduino-Core MK22 is a 32-bit microcontroller development core board with the MK22FN512VLH12 as the core, and it is an open-source controller module.

Microduino-Core MK22 integrates USB communication, and its pins meet the microduino specification.

Microduino-Core MK22 uses the development environment of mbed platform C++ language. Players can use Microduino and other electronic components, modules and sensors to make abundant funny interactive works.

Features

• The microcontroller is based on Cortex-M4 kernel；
• CPU frequency can achieve 120MHz；
• Small, cheap, stackable and open；
• Open-source hardware circuit design, and compatible-with-mbed development environment；
• Support USB function；
• Unified Microduino interface specification, and abundant periphery modules, which can be quickly extended and connected with other modules and sensors which meet the Microduino interface specification, conveniently and flexibly；
• 2.54-spacing female header connector interface is convenient for integration to the pegboard.
