Freedom Development Platform for Kinetis® KV3x Family MCUs

FRDM-KV31F

Roll over image to zoom in

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® Rev3 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.
