Before buying an Ultimate GPS Shield I am concerned about two potential incompatabilities.
Can I run the shield on 3.3v power and data signals? I know both the GPS and SD actually just need 3.3v. But I am not certain the design of the shield has assumed 5v power and data signals by default.
Would the SD card run on SoftSPI when the shield is connected to a Leonardo? Because it seems to assume that SPI is on pins 11, 12, 13. But they are only available via ICSP on the Leonardo.
If anyone could provide their opinion on this.
