BrundleFab - a 3D Printer Experiment

Design Notes

Connecting an Arduino Mega2560 to a Seed Studio SD Card v3.1 Shield

Well, it doesn't just snap on and work. You need to route some pins:

MEGA Pin SD Shield Function
ICSP1 D12 MOSI
ICSP2 5v 5v
ICSP3 D13 SCK
ICSP4 D11 MISO
ICSP6 GND Gnd
D53 D10 SS

Use the arduino SD library, with a 'const int chipSelect=SS;' and you are good to go.
