custom carrier board

im making a custom board for the micromod ecosystem

Is this ok?

I think i will use the esp32 but i want micromod if i would need to change the processor later.

Some questions:

1

Can i leave “BATT_VIN/3” unconnected, and use the internal reference for the ADC? (i might remember wrong, but i think BATT_VIN/3 is for adc ref voltage?)

2

my board needs no power saving/sleep, can i just ignore/leave unconnected “3V3 enable” ?

3

I wont have any battery or rtc, can i ignore/leave unconnected the “RTC 3V” ?

4

is it ok the leave “USB VIN” unconnected? i have a 3.3v regulator that uses 5v from the usb connector on my board?

Thanks for reaching out to us on this.

This beyond the realm of Technical Support’s expertise (delving heavily into Electrical engineering consult-work), though we will leave the topic open in case someone in the forums has something to offer that may be of further assistance.

Hope this helps, and happy sparking!
