Minimum required pin for High Accuracy Pi RTC

#1

I’d like to know minimum required pin for High Accuracy Pi RTC’s header.

I think…
[list]

  • [*]3: GND
  • [*]6: RST
  • [*]7: S/INT
  • [*]10: SCL_3V3
  • [*]11: SDA_3V3
  • [*]12: 3V3
    • [/list] that's enough?

    Hi ,

    The pin count depends on which communication protocol you are using between the RPi and the RTC module.



    and you listed I2C Communication pin names.
