TECHNICAL SUPPORT NULA Development Boards

Hello,

I’m working with the NULA DeepSleep ESP32-S3 board.

Which ESP32-S3 GPIO is the onboard PCF85063A RTC alarm (INT) pin connected to? I’d like to use the RTC alarm to wake the ESP32 from deep sleep.

Thank you!

Hello @Tovaxo
It’s connected to IO17. The hardware files for this board are not published yet, but I’m attaching the schematic here so you can see it directly.
