低功耗stm32l073

你好，
我正面临着关于STM32l073低功耗的问题。在我的核板NUCLEO-L073上，当我进入停止模式时，我的消耗量大约是1和3uA，所以一切似乎都没问题。然后，我们决定制作我们自己的板（参见附件），使用相同的代码，我消耗大约30uA，我真的不知道为什么???唯一的区别是封装，根据我们自己的设计，我们使用的是stm32l073 LQFP48（48pin），而在核心上，这是64个引脚。由于我不是电子专家，我不知道如何调查这个问题。
如果您对可能出现的问题有所了解，或者我做错了什么，请不要犹豫，分享。
先谢谢你，
最好的祝福，
Aurlien

Hello,
I'm facing an issue regarding low power on stm32l073. On my nucleo board NUCLEO-L073, when i go in stop mode, my consumption is around 1 and 3uA, so all seem to be ok. Then, we decided to make our own board (cf. attached file), with the same code, i consume around 30uA and i really don't know why ??? The only difference is the package, on our own design, we are using a stm32l073 LQFP48 (48pin) whereas on the nucleo this is a 64 pins. As i'm not an expert in electronic, i don't know how to investigate this issue.
If you have idea about the possible issue, or if i'm doing something wrong don't hesitate to share.
Thank you in advance,
Best regards,
Aur�lien
