FRDM-K28FA

FRDM-K28FA is a low cost development board for Kinetis K27 and K28 high-performance MCUs based on Arm® Cortex®-M4. This board features MK28FN2M0VMI15 MCU which features a high-speed and full-speed USB controller with available crystal-less operation, SDRAM controller, secure digital host controller, QuadSPI controller, and analogue and digital peripherals. The FRDM-K28F H/W is form-factor compatible with the Arduino™ R3 pin layout, providing a broad range of expansion board opts. The on-board interface includes a 6-axis digital accelerometer and magnetometer, RGB LED, FlexIO socket, SD card interface, mobile SDRAM memory, external serial flash memory. FRDM-K28F features OpenSDA v2.2, open-source H/W embedded serial and debug adapter running an open-source bootloader. This circuit offers several opts for serial communication, flash programming, and run-control debugging. OpenSDA v2.2 is an mbed™ HDK-compatible debug interface pre-loaded with the open-source DAP link interface firmware.
