Adding the SPI connector will not convert it to the SPI version. we currently flash the controller on the board for the version that you order. We're contemplating if we can make the software auto-detect I2C or SPI. The LCD itself requires 5V.  -- REW</ins></div></td></tr>

The SPI_LCD module has two 4 pin connectors (in & out), I do not know the pin-out of these. The 4pin cable does not match the 6 pin header on the RPI_SERIAL Board's SPI0 connection. How do these boards interconnect? Does this LCD require 5v or 3.3v?</div>Electric Bob
