Oww.. thanks for the enlightenment - I hadn't understood the '0' of the ESP32 world
ESP32-DOWDQ6
vs the ESP32-S2 or ESP32-S3

I'm revaluating. I need low power sleep (or power off), TF card slot, 3 UARTs, Wall Time RTC , 16MB flash with at least 2MB program space and OTA capability- and that is narrowing to a ESP-S3 and possibly a M5-CoreS3. Though I'm also want to plugin Cell LTE ~ Possibly Cell Modem U128 and RS485/Switched 12V - so needs external power with solar panel.
I liked the switched port power on the M5station - oh well.!
USB OTG would be extensible to have - especially USB Host if the software is available.
