Lucerne University of Applied Sciences and Arts Launches tinyK22 Educational Dev Board V1.3

Available to purchase from PCBWay, the new board has a range of improvements over the original in-house design.

The Lucerne University of Applied Sciences and Arts has launched the latest version of its tinyK22 board, a development board designed for everything from lectures and labs to research projects — and it now comes with a microSD slot populated by default.

"The tinyK22 board is a tiny microcontroller board we use at the Lucerne University of Applied Sciences and Arts," explains Erich Styger. "It is used in many research project, used in lectures and labs and used in most student projects. Because there was no small and breadboard friendly NXP Kinetis board with a debug interface available, we developed one featuring the NXP K22FN512, named the ‘tinyK22‘. Because of the success and high demand we stated a new large production run and used this to upgrade the board to the new Rev 1.3."

"The board is a breadboard-friendly, inexpensive and universal Arm Cortex-M4F which can be easily used for a broad range of projects. The board incorporates the OpenSDA circuit and is basically a stripped down version of the popular NXP FRDM-K22F board. The board works with GNU Tools for Arm Embedded and can be used out-of-the-box with the NXP MCUXpresso IDE and SDK, or any other custom IDE or tool chain for the K22F512."

While the most obvious change between the revisions is a shift from a green PCB to blue, there are bigger alterations two: The underslung microSD card slot on the rear of the board is now populated by default, the board now supports a Tag Connect cable, and a diode on the reset line fixes a potential bricking issue if a bad program is flashed.

The biggest change of all: The board is now available outside the University. "So far the board has been used in-house for research and education," Styger notes. "We received frequent requests if we could sell that board. Because we now manufacture and assembly the boards at PCBWay, we published the design and manufacturing files. That way everyone can order boards from there too."

The board is now available to order from PCBWay, while more details can be found on Styger's website.
