    • RE: Stamp C3U - Maximum GPIO input voltage?

      Hi Felix,
      thank you for your fast reply.
      I've used different Atmega, Attiny and STM32 based boards in the past, but new to ESP32. That's the reason for my "stupid" question. ;-)

      Thanks again.

    • Stamp C3U - Maximum GPIO input voltage?

      Hi,

      I want to use the internal ADC of the Stamp C3U. What is the maximum voltage, that can be measured? 3,3V or 5V?
      I don't understand the meaning of the feature "Stamp-C3 contains 5V->3.3V DC/DC design". Does it mean, that there is a level shifter? Or does it mean, that the inputs are 5V tolerant? Or does it just mean, that 5V are accepted as power input?

      Thanks.
