Teensy-based Single Board Computer
The Teensy is a powerful microcontroller development board, featuring an ARM Cortex-M7 processor running at 600MHz. It far outstrips the performance of earlier Teensy generations as well as other popular microcontrollers like the ESP32 or even Cortex-M4 based boards. With all this power, there’s a huge number of possible applications. And now with this Teensy 4.1 Computer board, it’s easier than ever to interface USB, audio and Ethernet to your Teensy application.
Because the Teensy uses a Cortex-M series chip instead of a Cortex-A (like the Raspberry Pi, for example) it’s not common to run Linux or any other full desktop operating system. However, for custom applications like digital synthesizers, homebrew game consoles or home automation systems, a board like this can be uniquely powerful. It’s like having a powerful single-board computer but being able to easily program it directly in C/C++, Arduino, CircuitPython, PlatformIO, or Visual Micro.
The floating-point performance is excellent, so a strong area for this board would be in audio processing and synthesis. The performance is further enhanced with branch prediction, another awesome feature new to the Cortex-M7. The Teensy also features a powerful DSP library that takes advantage of the DSP instructions inside the M7, so many channels of audio can be streamed and modified simultaneously.
If you’ve wanted to expand your Teensy projects, or you’ve been meaning to check out the new Teensy 4.1, this is a great way to do it!
