I have recently purchased some relay8 boards to control some relays in my switchboard, and I have just started playing with them. I have bridged the “Link DC Input and VIN” jumper, used the example code on a Freetronics Eleven and it works as expected. However when I shift the shield onto an EtherMega, the green power LED adjacent the 5-24Vdc in does not illuminate, and the relays do not fire. I intend on using four of these shields stacked onto an EtherTen in production, and I am assuming I will find the same issue with that board as the EtherMega.
Is there some weirdness with the EtherMega that I am not aware of?
Is anyone using relay8 boards and have some code examples they would like to share?
