External Pull-up / pull down for strapping pins

Postby FCT_IOT » Sat Feb 03, 2018 11:56 am

Dear all,

I would like to know if a 4.7 Kohm external pull up or pull down is sufficient for the Strapping pins. I will be powering the ESP-WROOM-32D Module with 3V Power supply. Hence Pull ups are connected to 3V supply.

Thanks in advance

Usually 10k are sufficient, though it depends what will be pulling them down if that is ever a use case in your setup. I'd check some reference drawings.
