I have run into an issue where my board emits a high pitched squeal (for lack of a better term) when a load is put on the board via the USB port. As soon as the load is removed, the noise stops. It only happens with a load and 5v booster turned on.

Really? It is pretty annoying it sounds like. I this got to be the 5V booster generating signal.
When and where did you buy your board? I want to check warranty status.

My setup is outside, and I rarely open the box. I chose to ignore it.

Well, you are out of warranty but we can issue you a coupon for a discount. PM me.

Well today I believe the booster officially died. Noise is still there but it will no longer power my pi. I tried multiple USB cables and multiple charged batteries.

I received the new board and it worked perfectly for three days before it no longer powered my pi; it will power an arduino uno. I unplugged the load and charged the battery through the board with no change to outcome. Switched batteries with no change. The pi works when powered through 5V 2.5A D/C power source but I am going to try another Pi Zero with nothing connected to see if the current draw may be too high. Considering it powers the Uno and not the Pi has me believing that may be the case. There is a camera attached to the Pi but the previous board worked for 6 months without issue. Any suggestions?

Hmm. Can you check the current going into your Pi by reading the i2c device on the board? That would really good to see how much current your system is drawing.
We power all sorts of devices with these boards. Even 3B+ Pis.

With a common ground, yes. SunControl has an I2C device on board that you can use.
