Hi, I connected an SX1509 to an arduino and have had it working perfectly on the same project for 2-3 weeks. But now all of a sudden it stopped responding, I havent changed any wiring or code. I went back and loaded the basic examples using your library for the SX1509 but the unit won’t respond now…

Sparkfun SX1509 suddenly stopped working, is it broken?

How was it being powered?
