Sdhc To Sd I Just Bought A R4dss Sdhc + 8bg Micro Sd And Was Wondering If It Would Work On My Ds?

I just bought a r4dss sdhc + 8bg micro sd and was wondering if it would work on my ds? - sdhc to sd

I bought an 8GB SDHC R4DS + Micro SD side and a Nintendo DS. I wonder whether it would be for my DS, because in a random site work that says I must be under 2GB. Can someone help me.
