Update 3/4: After receiving the replacement, I was able to verify that the LED is lit and the circuit board is working. Please note that the LED does not indicate power, but an active USB connection. However, as my Nano was also dead on arrival, I am awaiting a replacement for this unit to continue testing. I'll update again once I can pair it with a working nano. Original Review: My board was dead on arrival. It was sent back via Revain. I will update if the replacement works.
