LoPy4 external RTC clock



  • Does the LoPy4 include a 32.768kHz crystal?
    I know the two XTAL32 pins can be configured as GPIO or XTAL32, but I have seen other modules with similar pinouts where the quartz crystal is included on the module, so I wondered if the LoPy4 is similar, or if I should add an external crystal and two capacitors to these pins?
    For my application, I do require an accurate RTC running including when the ESP32 is in deep sleep mode.
    Thanks.
