The TWR-K65F180M is a development board for the Kinetis K26, K65 and K66 180 MHz 32-bit Arm Cortex-M4 MCUs. It features the Kinetis MK65FN2M0VMI18 low-power MCU with 2MB Flash, 256 KB SRAM, HS USB and Ethernet MAC.
The FRDM-KV31F is a low-cost development tool for the Kinetis V series KV3x MCU family built on the Arm Cortex-M4 processor. The FRDM-KV31F hardware is form-factor compatible with the Arduino R3 pin layout, providing a broad range of expansion board options.
The TWR-KM34Z75M board is designed to work either in standalone mode or as part of the Freescale Tower System, a modular development board platform that enables rapid prototyping and tool re-use through reconfigurable hardware.
