I have an Arduino Mega that needs to have an Ethernet shield and an expansion shield.
As I have to mount the Ethernet shield first so it can use the ICSP pins, I then cannot stack the expansion board correctly as the Ethernet shield is only UNO sized although sold as and works as Mega compatible.
If I then put the expansion shield on top of the Ethernet shield, I only get the UNO equivalent of pins.
Can I add headers to the MEGA, at the bottom of the stack, so that the expansion board will marry up to the Mega? Although I think 1 or 2 pins will be blocked out by the Ethernet boards edges.
At the moment I seem to need to utilise 3 or 4 sets of headers to get the correct height. Is this the correct way to go about connecting it all together or is there an easier way?
Appreciate any advice.
