ESP32 External RTC crystal Component Selection
Posted: Thu Dec 01, 2022 8:26 am
Hello,
I am working on the Project in which I am using ESP32 WROOM 32E and this Project will be Battery Operated.
So my question is regarding using of External Crystal (RTC) and for that as per the Datasheet i have made connections of Crystal Oscillator and its Components.
As you can see in attached image;
1) You have given the Resistor value in the Range of 5M ohm to 10M ohm. So If I get 5M ohm then what will be the Impact on performance of Crystal and same question for 10M ohm Value.
2) Can you suggest us the Crystals and its Capacitor values?
3) Suggest the Value of R3 and R5 Resistors.
