    ICSP - SPI header on reference board - 5 Volt PSU pin - SPI signals 5 Volt compatible?

    fweerdenburg@eltan.com

      The CRB of D2000 has ICSP header. For example to connect SPI to an Arduino WIFI shield.

      This header is also used on Galileo - Quark X1000 board.

       

      On Galileo board the SPI signals are converted from 3.3 Volt to 5 Volt level.

      The CRB of Quark D2000 does not have this voltage level conversion.

       

      Can you explain this different implementation?
