TWR-K21F120MA

TWR-K21F120MA is a Kinetis® K21 120MHz Tower® system module. The TWR-K21F120MA is a development board for the Kinetis® K21 and K22 120MHz 32-bit Arm® Cortex®-M4 MCUs with floating point unit. The board provides rapid prototyping for applications requiring high feature integration, as low as 240µA/MHz low-power consumption and mid/high flash memory density (up to 1MB) that need to support multiple communication stacks.
