    1 TWR-K70F120M and TWR-K70F120M-KIT Overview The TWR-K70F120M is a development board for the K61 and K70 family 32-bit ARM® Cortex™-M4 MCUs. The TWR-K70F120M is populated with a device rated for 120 MHz operation across the full -40C to 85C temperature range. At room temperatures the board can be over-clocked to 150 MHz to allow for evaluation of the K70 and K61 devices that are rated for 150 MHz operation across the full temperature range.
