I'm currently prototyping a mobile gadget that makes use of Nokia LCD Shield
), an 3-axis accelerometer, a light sensor and a Zigbee wireless module. All this on a Duemilanove.
It gets crowded.
Now I want to try to get a proper amount of images on the display and thus I want to have some extra space. I was thinking of adding an SD
) card reader to the prototype.
My problem is however, that the Nokia shield uses the digital inputs 8-13 and GND and AREF. The Zigbee shield takes up the digital pins 0 and 1. That leaves me with digital pin 2-7 (six in total) to use with the sd card reader. Looking at the schematic for the microSD card, I should be able to to this, since it appears not to need the NC pin connected and the GND can be wired to another ground on the Arduino.
Am I correct in this? Or am I overlooking something? It would be a shame to order the readers and then discovering that it won't fit.
