Roll over image to zoom in

The TWR-K21F120MA is a development board for the Kinetis® K21 and K22 120 MHz 32-bit Arm® Cortex®-M4 MCUs with floating point unit.

The board provides rapid prototyping for applications requiring high feature integration, as low as 240uA/MHz low-power consumption and mid/high flash memory density (up to 1 MB) that need to support multiple communication stacks.

For TWR-K21F120MA availability using MK21FN1M0AVMC12 MCU, contact your local NXP® Sales Office.
