Any chance we could get a picture of this with the normal rulers?

The code in the wiring example is needlessly slow - I replaced the delay(2) calls with delayMicroseconds(1), and it seems to work (but I have not tested it rigorously).

According to the datasheet and the data above, it works at 3.3V, however in wiring example it is connected to 5V. Which one is correct?

Please be aware, that this device is pretty slow and according to the datasheet you have to keep the chip select line down during the whole sampling process. This slows down all communication on the SPI bus. So if you have other slaves on the same bus read the datasheet carefully!
