AD noisy? (No)

  • The SDO112A fed the M5 with quite a clean signal and got something very noisy on the Oscillo @Calin made.
    Is the AD input of the esp32 noisier than an stm32 or the old arduino, is this the amp that M5 hardware added?

  • After disconnecting the M5 from the computer and grounding the source, the sampled signal is very clean.
