I finally started putting an auto-plant-watering system together, trying to develop the entire system using Win10 IoT, VS 2015, and c#. I'm at the very beginning stages of development but I did get the moisture sensor reading and LEDs lighting up successfully.
Last night I planned on continuing development but when I got home the Pi was off. Weird. I had left it on the previous night with only Win10 IoT running. The Broadcom chip on the Pi was extremely hot. Like, burn your finger hot. I immediately unplugged the unit and let it cool down for a few hours. When I tried to power it back up the first time, the power LED came on but not the ACT. Subsequent power cycles eventually led to a fainter power LED, and then eventually no LEDs on the board coming on at all. The Pi now looks to be completely dead.
I tried another power supply that is known to be working (from a different Pi running Raspbian) with no luck. I also moved the SD card from my Pi to a working Pi and it booted right up (so it's not the SD card).
- There is nothing but the Win10 IoT image installed on the SD Card
- I am using Visual Studio 2015 to develop and debug
- The code above worked perfectly fine the night before the Pi died
- I left the board sitting on a chair in my office with just the power supply plugged in. The chair has a cloth seat so the bottom of the board was sitting on the cloth (is that bad?)
- The Pi was connected to my breadboard that had the working circuit (moisture sensor and LEDs) connected to it
- The Pi also had a USB WiFi dongle attached prior to the issues
- the HDMI cable was NOT connected
- All the power cycling described above was done after removing all connected items (nothing attached) to the board.
- I also tried removing the SD Card and powering it on...no luck there either
- Testing with a DMM on my original power supply I get 4.5V on the PP2 pin
- Testing with a DMM on the second power supply I get 5.1V ont he PP2 pin
Is there anything I can do or is this thing hosed?
