Overview

The FRDM-KV31F is a development platform for the Kinetis KV3x family of microcontrollers, which are specifically designed for BLDC and PMSM motor control applications. This Freedom series board features an ARM Cortex-M4 core with a Floating Point Unit (FPU) and is equipped with an onboard OpenSDA debug adapter for easy programming and debugging. It provides a low-cost entry point for engineers developing high-performance motor control and power conversion systems.

Why Choose This Part

This board includes an integrated 6-axis digital accelerometer and magnetometer (FXOS8700CQ) and an RGB LED for immediate prototyping of motion-aware applications. Its compatibility with the Arduino R3 pin layout allows for easy expansion with various shields, while the OpenSDA interface eliminates the need for an external hardware debugger.

Applications

Brushless DC (BLDC) Motor Control
Leverages the KV3x advanced timers and ADC performance for efficient motor commutation.
Permanent Magnet Synchronous Motors (PMSM)
Utilizes the ARM Cortex-M4 FPU for complex vector control and field-oriented control (FOC) algorithms.
Power Conversion
Suitable for digital power supply control requiring fast analog-to-digital sampling and PWM synchronization.
Industrial Automation
Provides a robust platform for developing distributed control nodes and sensor hubs in factory environments.
