Nucleo-L496ZG in 1.8V

Question asked by Philemon Jaermann on Mar 21, 2018



I have a nucleo-L496zg board (stm32L496ZgT6 144 pins) and I'd like to use it in 1.8V.

From the document UM2179, section 6.5.4 I see that it's possible depending of the connection on SB121, SB122

and SB127, which I changed accordingly (SB122 open, and SB121 and SB127 closed).

However, the board still seems to be operating at 3.3 (UART idle state at 3.3V). Looking at the board schematics from here

NUCLEO-L496ZG - STM32 Nucleo-144 development board with STM32L496ZG MCU, supports Arduino, ST Zio and morpho connectivit… 

I can see the chips needed to operate in 1.8V, like U10. The problem is that those chips are not physically present on my board.


So is there a way to switch this board to operate at 1.8V (and keep the STlink V2)?

Or which board package should I buy to have the needed chips on the board?
