Stacked mega and ethernet/sd shield:
When I do this stacking, it heats up. I tried connecting the SPI via ports 13-10 (no stacking), it doesn't work. Also tried connecting the ICSP (red circled mark) via male-female wires without stacking, it works, but still heats up. So I think the ICSP has a defect? or does it? Is it supposed to be like this and I'm just being paranoid?
*PS: the heat in the "pain" level when I touch it, no burning IC odor. Maybe it's because I unplug it immediately after short use? IDK.
**update, I think I got it working, the problem was not about the heating, but the program. Consulted a more experienced person, he said what's happening is normal.
