I recently came across one of the boards and I didn't have the hardware to sacrifice the provided 3.5mm audio jack so I decided to play around with the board to see if there was a place I could solder and get the same data from the board. I found one and I got an accurate read. Would you like to see how I did it?

Hello, you can solder a jumper wire at output of opamp if you don't want to cut audio jack :

Don't use red led signal due to the presence of monostable circuit (you will lose precision)
