3 out of 5 NX Devkit carrier boards have failed now. In each case, they’re essentially presenting a dead short to the 19v power supply. Anyone else?
Nothing special about the setups. No USB peripherals, nothing connected to the 40 pin header, using the supplied 19v power supply. Each time though, the module was doing heavy compiles using all 6 cores at 100% and with the fan spinning at 100%. I’m wondering of the carrier board input regulators are shorting out from the load. The modules themselves are fine. I can swap them to one of the two remaining carrier boards with no issues. Unfortunately though, I now have 3 perfectly good NX modules without anything to put them on.
The carrier board specification lists the input regulators as TPS53015 for both 5v and 3.3v but the only info I can find on them says they’re rated for only 120ma so that can’t be right. Anyone know that they really are?
