    Development board level shifters

    IlieGalan

      Hello,

      We have two Intel Joule development kits, one containing the 550x module and the other containing the 570x one.

      The problem we are facing is that the voltage level of the signals on the J12 and J13 connectors are only going up to 1.8V instead of 3.3V as specified in the datasheet.

      On J13 for example I can successfully measure 5V on pins 2 and 4, 3.3V on pins 6 and 8, and 1.8V on pins 10 and 12 but when I try to output a signal on the SPI port, it only goes up to 1.8V instead of 3.3V.

      This is happening to on both development boards.

      I does anyone have the same problem, is there a issue with the level sifters?

       

      Any help is appreciated,

      Ilie
