Voltage issue on an esp32 wvroom 32D development board I have an esp32 wroom 32 dev board. I'm running into power issues and I'm not sure what's going on. 

When I try to upload sketches the uploads fail if I have any jumpers running to the 5v or 3.3v pins which is weird. 

Also, when I have nothing plugged into the board other than the usb cable and try to measure voltage across the ground and power pins I get 1.5v from the 5v pin and 0 from the 3.3 pin





This is a brand new out-of-the-static-bag board and I'm having the same issue with another board of the same type. 

I feel like there's something I'm missing. Any ideas?
Try measuring the voltage against a different ground pin? I had a similar problem and discovered the pin next to the 5v input pin wasn't actually ground. Not sure why this would affect sketch uploading though..
