WiPy Vbatt input pin

  • Hi all,
    seems that WiPy OeM Hw do not provide a Vbat input pin in order to connect a battery or supercap in order to maintain power on internal RTC in case of primary power lost.
    ESP32 provide this input pin but seems not extracted on WiPy hw.
    It is true ? if yes the only way to maintain time date info is to use an external RTC on i2C bus. I'm right ?
    Thanks in advance
