adafruit data logger shield not working

Is there any way to check if I wired it wrong?

for adafruit product help, post in the adafruit forums

You may find bits of the stuff I’ve posted about the NuElectronics datalog shield useful…

You don’t narrow “doesn’t work” down much for us.

You could replace the Adafruit shield with the NuElectronics one for about $16 + p&p, and then the info above would be directly applicable.

And no, I have no connection with NuElectronics beyond happy customer.
