Well, I'm not sure if I broke it or my step down controller just burnt out and took it with... but my nano router is dead!
It was the chinese nano router though, so its only a $17 loss, but the week-longer wait for a replacement hurts the most! I thought I bought a TL-WR702N from TPLink, but this is what came in the mail...
I spent a while configuring it, got it working with my network and rasperry pi, and then I go to solder it into my radio. On this radio, I had the power switch on the ground leg, which was fine until I hooked up this router. It was weird, but ground was flowing back from this router to the whole radio causing it to turn on even when the power switch was off.
To remedy it, I just swapped the power switch over to the positive side, and let all the grounds stay in circuit. I should have done this to begin with, I'm not sure why I thought it was better to switch the ground... But it did work after I sorted that out... for a few minutes... then the step down controller got really hot and pushed 7 volts out. This is what seemed to kill the router.
The Rpi was hooked up too, thats how I noticed something was wrong. The Rpi power light was on, but very dim. I quickly unhooked power and sorted things out.. but the router never came back. I tried tracing the power path but it looks to go right into the BGA cpu chipset... which doesnt get warm anymore so I think it's fried.
At least the Rpi seems to be OK... again, just $17 for the router but this still sucks! I hate when I fry things!
