先来两张FRDM-K28F的整体框图来感受一下

再来两张实物拍摄

FRDM-K28F整个板子的特性描述如下：

• Kinetis MK28FN2M0VMI15 MCU (ARM Cortex-M4 at 150 MHz, 1MB SRAM, 2MB flash, HS and FS USB, 169 MAPBGA package).
• Kinetis K20 MCU (K20DX128VFM5) based OpenSDA circuit.
• Dual-role high-speed and full-speed USB interface with the micro-B USB connector via the high-speed switch.
• One 256 Mbit (32MB) on-board QuadSPI memory at 1.8V.
• One 128 Mbit (16MB) on-board mobile SDRAM memory at 3.3V.
• Multiple independent voltage domains: VDD_CORE, VDD, VBAT, and VDDIO_E.
• FlexIO socket which enables you to connect an optional TFT Proto 5” CAPACITIVE from MikroElektronika (5” display board with capacitive touch).
• Easy access to the MCU input/output through Arduino R3-compatible I/O connectors to connect external add-on boards.
• Flexible power supply option—OpenSDA v2.2 USB, Kinetis K28 USB, or an external source.
• RGB LED
• Two mechanical push-buttons for user input and one for the reset.
• Programmable OpenSDA v2.2 debug circuit supporting the DAP-Link interface software which provides:
  
  • Mass-Storage Device (MSD) flash programming interface.
  • CMSIS-DAP debug interface over a driverless USB HID connection providing run-control debugging and compatibility with the IDE tools.
  • Virtual serial port interface
  • Open source CMSIS-DAP software project
    

    FRDM-K28F首先是一块颜值超高的板子，其使用的MCU为NXP的MK28FN2M0VMI15。主频有150MHz，算是比较高了。除了超大的片上存储空间，另外板载还有32M的Nor flash和16M的SDRAM。加上这次的活动真的超值，野火家某个16MNor flash和8MSDRAM的核心板都一百六七十了。
    此开发板亦有兼容Arduino 的接口，此外还有RGB LED，三轴加速度计，USB，按键，电池座，SD卡座以及开源的调试器等等。总之是个活动时十分值得入手的板子。
