FRDM-K28F No Longer Manufactured

Roll over image to zoom in

The FRDM-K28F is a low cost development board for Kinetis K27 and K28 high-performance microcontrollers based on Arm® Cortex®-M4

  • Enable rapid prototyping, including a 6-axis digital accelerometer and magnetometer to create full eCompass capabilities, dual role high-speed and full-speed USB interface with Micro-B USB connector, a microSD card slot a tri-colored LED and two user push-buttons for direct interaction, 1x256Mb QuadSPI external flash, Mobile SDRAM, FlexIO-based LCD socket, and light sensor

    *Note: FXOS8700CQ accelerometer is in “End of Life” status

  • Form-factor compatible with the Arduino® Rev3 pin layout
  • Feature Core Voltage Bypass (Available on K28 only)
  • Include NXP open source hardware embedded serial and debug adapter (OpenSDAv2.2) running an open source bootloader, which offers options for serial communication, flash programming, and run-control debugging

The FRDM-K28F is enabled using NXP MCUXpresso Config Tools, MCUXpresso SDK, Power Estimation Tool, and MCUXpresso IDE and a large software partner ecosystem (please check Download tab).
