I'm using a MKR1000, attached I have an NFC module and an Arcade button. When I attach them directly to MKR1000 it works as expected. When I add an Arcade Button to it, it won't work as expected, as there is not enough power (light is low, and get signal from input that the button is always pressed)
Wiring is as follow MKR 13 RX to Button Light MKR GND Button Light MKR 9 SKC Button Click MKR GND Button Click MKR GND NFC Shield
So I have multiple things attached to GND, but as said, issue only shows when MKR ETH SHIELD is inbetween. Any ideas?
Is there any mode to add additional power to the Shield or Button? Is the issue the GND chaining of all 3 devices (NFC, BUTTON, BUTTON LIGHT) ?
Thanks for any help
