I am hoping the power issue is literally a GPIO pin not being soldered correctly but I am not sure how to test.
When I plugged everything in, I did not get a power LED on on the Pi Zero and no image on the screen. Here are my questions.
1. Is the VMU board meant to make electrical contact with the DM and DP pads and the micro USB ports pads? I just want to make sure I put solder there when I was supposed to.
2. I was able to test a lot of the GPIO test points but there were plenty I couldn't figure out the locations to, such as:
- * 3.3V
* LCD DC
* LCD MOSI
* LCD MISO
* LCD SCK
* LCD BL
* AUD BCLK
* BATT MON
* LCD RESET
* LCD CS
* AUD DOUT
3. Finally, this is the weird part - when plugged in and turned on, the whole unit (not sure if it's the Pi or VMU) makes a very consistent, almost once per second clicking sound. It's very subtle but definitely happens 100% of the time and never changes frequency.
Any advice would be appreciated. If I could do it again, I probably would not have removed the ports since I am not sure I even want or needed a larger battery. Thank you.
