Si4713 challenges
I am having trouble getting my Raspberry Pi 3B+ to recognize the SI4713 FM radio board I just purchased. It does not show up with i2cdetect in the 0x63 spot it should. I tested the voltage coming from the GPIO at 4.4V with a multimeter, but when I connect up to the Si4713 and test the voltage on the pins, I see 0.6V. I'm thinking this is the issue. My pi does not have an undervolt warning. Can someone check my soldering?

Re: Si4713 challenges
Try going over the pins one more time. It looks like you have enough for a connection, but the amount of solder is minimal.
Can you show a photo of how you have the board connected to the Pi as well?

Re: Si4713 challenges
Thank you for the response!
I actually felt like I applied too much solder and it keeps disappearing. I believe that it seeped down the pins and sits in a channel in the plastic pin holder, which I thought was shorting out the input voltage to the GND. I bought another one, was more careful with the solder, but I'm still having the same issues where the Pi does not see the board using sudo i2cdetect -y 1.
Here is a picture of my wiring to the Pi. I can try eliminating the cable and wiring directly to the Pi, but that should have no effect on the input voltage, no?
Thank you for the help! I need to get this working.

Re: Si4713 challenges
SO, I removed the GPIO extender and it is working now.
Thanks for the help.
