Arduino/Raspberry Pi component compatability?

  • Pico-12 Friday, November 21, 2014 3:48 PM Reply
    Could someone please advise a noob about the compatability of components "for Rasberry Pi" with Arduino boards? both in general, but also specifically cameras such as the Waveshare Night Vision Camera (SKU 347317)? Can this be connected to an Arduino?
    (ultimately the idea is to connect a motion sensor too, and an SD card for storage)

    Yes, it's compatible.

    Arduino shields that require a 5V input/output will NOT work with the R-Pi.

    One such example is the ACS712 current sensor, which works on 5V, and is not tolerant on voltages below 4.5V. Basically, anything that is not 3.3V tolerant will NOT work on the Raspberry Pi.

    There are means to work around the 3.3V-5V limitation, like using level shifters (such as the CD4050), but that is quite troublesome. Your best choice is to use sensors or actuators that are tolerant to both 3.3V and 5V.
