Shdwdrgn, I have one of those also, and I think I may wire it in permanently just for looks. I don't use it so it's just in the junk box for now. Might as well put it to use. The Mustool does have an I2c Arduino bus decode function also, but its the display that's makes it the easiest to read meter. I would not buy the Mustool for its Oscilloscope function only.
