Teensy boards provide high‑speed ARM Cortex‑M7 microcontrollers in a compact footprint, delivering processing power that comfortably handles demanding real‑time control, audio processing and complex sensor fusion. They offer a range of memory options, from several megabytes of flash to generous RAM, plus optional Ethernet, USB host, and micro‑SD interfaces for networking and data logging. Compatibility with the Arduino ecosystem and a variety of stackable headers makes integration with existing shields and breadboards straightforward, while lockable fuses and copy‑protection features address code security concerns. The modular connectors enable rapid swapping of peripheral modules such as audio codecs or M.2‑style extensions, giving flexibility without sacrificing reliability. These attributes combine to suit projects that need fast computation, extensive I/O and easy prototyping in a single, robust platform.
