  • Hmmm I am using a Piezoelectric Fiber Composite from ACI, which is listed on Table 2. My oscilloscope shows a peak voltage of about 40V, maybe that is too much for the breakout board?

    OK so here is what I am doing to test the LTC3588: Arduino Uno 5V -> LTC3588 Vin, Arduino Uno GND -> LTC3588 GND, Oscilloscope + Probe -> Vcc, Oscilloscope - Probe ->GND (different GND on the same side as Vcc)

    When I measure Vcc I am not reading any voltage. However, when i move the + Probe to D1 I am reading about 5V...what do you think?

  • hi, i have set up my breadboard in the same way but the LED will not light up. Will this only work with a certain piezo? Is there a way to test the LTC3588 to make sure it is working properly?

No public wish lists :(
