  • This is not at all what that resistor is for. The phase shift arises from a single capacitor in the feedback path of the oscillatory circuit. The second capacitor exists for reasons relating to RF reflection that I will admit I do not understand enough to explain. The feedback resistor is in place for biasing the internal amplifier. The circuit is inherently unstable and will oscillate.

  • Why is this so expensive? The chip is $2 and the USB connector you have is slightly more than that. I’m not trying to hinder your sales, but I just purchased a similar device (with a standard USB connector) that already has soldered headers for $5. I just ordered some other equipment from here, but this was just too expensive for what it is.

No public wish lists :(
