I recently received my Seeeduino Stalker V1 (328P). I have been playing around with the RTC, SD Card, and XBee functions. So far everthing seems to work great.
However, today I had my Stalker connected to the UartSBee with nothing else connected (except for an SD Card) and I touched a small chip and burned my finger! This little chip was so hot that I couldn’t touch it for more than about 1/2 a second!
I’ve circled the chip in question in the picture below. From the schematic, I believe this is the PCA9306 which is a level shifter chip. Is this correct? If so, I have to assume that I’ve somehow destroyed the chip. Any idea how I might have done that? I don’t really understand what the chip is good for, so I’m not sure what impact it will have on my projects.
Any help you can provide would be appreciated.
