ESP32 Regular Mode of Operation

Community General Discussion
1

Hi,
I am having difficulties figuring out which pins to pull up/down for standard mode of operation after programming has been completed.
I believe EN pin is pulled up via 10k
IO02 is pulled down via 10k
IO00 is pulled up via 10k
Is that right? and Is there any other pin I should be pulling?

Which ESP32 board do you have ?

3

It is WROOM-32E

4

That is the ESP32 module. Is it on a development board or standalone ?

5

It depends what you want to achieve. Can you post a schematic?

6

I have Programming module and standalone mcu. I will upload schematic shortly

7

Has the OP looked at other development board schematics to see how they did the thing?

9

I have looked into some of it, and most of those include programming module which i don't need.

10

Any ideas?

12

Have you breadboarded and checked the circuit, that would tell you if you are using any pins that might cause the ESP32 (or the rest of the circuit) problems ?

13

I have tested circuit + ESP32 module with the programmer in it. It works just fine. But it doesn't work without programmer.

14

I think i found solution.
EN should be pulled up
IO5 should be pulled up
IO12 should be pulled down
IO15 should be pulled up
