Hi. I have an evk2 with he910 that I cannot get to power on. I watched the videos, reviewed the user guide and jumper settings. I am using the included 12 V 1.5 A (120V AC) power supply that was provided. I verified power to the barrel connector is 12V. When I push the power button on the radio board (he910) I see power mon pin ramp up to about 1.7 volts then it falls back to 0. subsequent press and hold cycles do nothing until a reset is pressed. Then I observe the same behavior – rising to 1.7 ish volts and back to 0. I have not tried running off a power supply at 3.8 v . Do you have any suggestions? Thanks.
So a longer press on the power on button won’t help?
Do you happen to have another interface board to try?
I tried up to 10+ seconds – same behavior. I didn’t want to use either of these boards with a new kit that I will unbox today. Should this kit be returned?
Of course if you have serious doubts about the correct hardware behavior please contact your Telit vendor and arrange a return.
I only have 1 other kit and can’t risk the time to get a new one if I damage the remaining one. I will arrange a return. consider this closed.

I have the same issue. Did a new board work?
