Topic: Arduino Due SPI Hearder for low voltage (2-2.5V) (Read 199 times) previous topic - next topic

Hi all,

I would like to use the SPI header of my Due board to communicate with my circuit (which required MISO,MOSI,SS and CLK all except operating 2.5 V)

When I use Due without any change the SPI is operating with 3.3 V (internal regulator). I would like to change this to 2.5 V (with AREF pin or changing the regulator? ).

Is there a way to use SPI pins with 2.5 V external supply?

Thank you

It seems you need a logic level converter from 3.3V to 2.5V (e.g. TI's AVCA(B)164245 or
AVCA(B)H164245 dual-supply bus-translating transceivers).
