Is there a difference between the Adafruit ethernet shield and the Seeed Studio ethernet shield from a programing standpoint? What ethernet shield is the best to use with Xod? I have the Adafruit shield for Uno and Mega. Has anyone been able to save to the SD card on the shield. I’ve been unsuccessful saving to the SD card shield but have been able to save to Adafruit SD card breakout board. I’d prefer to save to the shield. Does anyone have a suggestions.
