  Hello,
  
  I'm doing some analysis on LuckFox Pico-Pro Max board and found something I don't understand.
  From the schematic it can be seen that VCC_VDDR is taken directly from 1.8V, however the datasheet for the RV1106G specifies that the maximum DDR_IO voltage is 1.45V, and reccomended is 1.35V.
  
  I have measured the voltage on the pin and I get 1.8V, so the schematic is correct.
  The board works, but I am wondering if this is a HW error or if the datasheet is not correct.
  
  Thanks
