    This might happen. But 2D GPUs provide only a few basic features, like alpha blending and bilinear scaling.

    SPI0 does not require pins 11 & 13. Alternate pins are possible, pins 7 & 14.

    Maybe this picture can help?

    If you use pins 7 & 14 for SPI0, then pins 11 & 13 are not used by SPI0.

    Using pins 7 & 14 rather than 11 & 13 is easy. From the example:

    #define SDCARD_MOSI_PIN 7
    #define SDCARD_SCK_PIN 14

    SPI.setMOSI(SDCARD_MOSI_PIN);
    SPI.setSCK(SDCARD_SCK_PIN);

    Then SPI...

    Message #144 talks of needed 4 separate SPI, one of them for audio. That doesn't make much sense to me. Maybe it's the French to English translation?

    One is a mature mass market product and the other is a first run eval board. Both are probably being sold at near cost. Notice the qty=1 limit and attempts to upsell related items on the Pi Zero.

    I believe you really need to be programming in assembly on an 8 bit chip, perhaps even 8051 or HC11, to qualify for old "you kids get off my lawn" geezer status.
