NXP Semiconductors K28F MCU的FRDM-K28F Freedom板

NXP Semiconductors FRDM-K28F Freedom开发板是一款适用于Kinetis^® K27和K28微控制器的评估平台。FRDM-K28F板规格兼容Arduino^™ R3引脚布局，提供了丰富的扩展板选项。板载接口包括6轴数字加速计和磁力计、RGB LED、FlexIO插槽、SD卡接口、移动SDRAM存储器和外部串行闪存。 FRDM-K28F包含一个运行开源引导加载程序的NXP开源硬件嵌入式串行和调试适配器 (OpenSDAv2.2)，它为串行通信、闪存编程和运行控制调试提供选择。FRDM-K28F可以通过NXP MCUXpresso配置工具、MCUXpresso SDK、功率估算工具和MCUXpresso IDE（集成开发环境）和大型软件合作伙伴生态系统启用。

The FRDM-K28F includes an 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 (Integrated Development Environment), and a large software partner ecosystem.
