LIS2DS12是否需要I2C上拉？

我正在使用STEVAL-MKI174V1适配器板进行LIS2DS12评估。我检查了STEVAL-MKI174V1的原理图，我有两个问题：

STEVAL-MKI174V1的Vdd可以是3.3V而不会损坏LIS2DS12，因为它只能处理2.2V（由于调节器，似乎答案是肯定的）我是否需要在适配器板上添加外部上拉到SDA，SCL线路？
谢谢，

I am using STEVAL-MKI174V1 adapter board for LIS2DS12 evaluation. I checked the schematic of STEVAL-MKI174V1 and I have two questions:

• Can Vdd for STEVAL-MKI174V1 be 3.3V without damaging LIS2DS12 because it can handle only 2.2V (It seems answer to this will be yes because of regulator)
• Do I need to add external pull-ups to SDA, SCL line even after adapter board ?
  

Thanks,
