    • Freedom Development Platform for Kinetis KV3x Family MCUs


    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, including FRDM-MC-LVPMSM and FRDM-MC-LVBLDC for permanent magnet and brushless DC motor control.

    The FRDM-KV31F platform features OpenSDA, the NXP open source hardware embedded serial and debug adapter running an open source bootloader. This circuit offers several options for serial communication, flash programming, and run-control debugging. The FRDM-KV31F is supported by a range of NXP and third-party development software.
