Unit appears to boot and then amost immediately shut down [don't install sd card for normal op]
Brand new unit, arrived this morning s/n 3172.
When I power up the 4 LEDs eventually begin cycling left to right and back which I assume is the unit booting. Eventually the 4 LEDs stop cycling and stay on but about 10 seconds after that all LEDs go out including the one between the USB A connector and the RJ-45 as well as the LEDs on the RJ-45.
Checking voltages, 5V measures 0.7V, 5VE measures 5.1V and 3.3 measures 0.0V, while booting same points measure 4.91V, 4.97V and 3.41V respectively. Just as the LEDs stop cycling I can see kiwisdr appear briefly on the list of connected devices on my router but it disappears again as the LEDs go out.
I've tried with two PSUs, same results, one a 3A rated wall wart style, the other my main bench supply - that is capable of 40A.
Any ideas / suggestions ?
thanks
