很幸运的抢购到了NUCLEO-STM32L496开发板，感谢社区的活动。开箱照：

NUCLEO-STM32L496也不带外部晶振，一个用户按键,一个复位按键，上电的例程都是通过用户按键控制三个LED的闪烁，上电默认亮红灯，按一下用户键亮蓝灯，继续按亮绿灯，以此循环。
使用外部LSE晶振 ：32.768KHz。
两个usb接口，一个是st-link用的，可以进行sw调试，u盘下载程序和虚拟串口。
另一个usb接口可以用于usb-otg和其他usb device。


板子的主要特性：（不翻译了）

Key Features

• STM32 microcontroller in LQFP144 package
• SMPS: significantly reduces power consumption in Run mode, by generating Vcore logic supply from an external DC/DC converter. This function is only available on ‘-P’ suffixed boards
• 3 user LEDs
• 2 push-buttons: USER and RESET
• LSE crystal:
  
  • 32.768 kHz crystal oscillator
    
• 2 types of extension resources:
  
  • ST Zio connector including: support for Arduino™ Uno V3 connectivity (A0 to A5, D0 to D15) and additional signals exposing a wide range of peripherals
  • ST morpho extension pin header footprints for full access to all STM32 I/Os
    
• USB OTG or full-speed device with Micro-AB connector
• 4 source options for power supply:
  
  • E5V from ST morpho connectors
  • ST-LINK/V2-1 USB connector
