ESP32 Forum

Hi,

at the moment I'm using this development board for my first tests and prototypes: http://www.smartarduino.com/view.php?id=95103

The final goal is to deisgn an own board which makes use of the ESP32-WROOM32 module without all the stuff that is not needed (USB etc) and for Bluetooth communication only.

So my question: is there an example schematic available which shows the minimum wiring that is needed in order to operate a ESP32-WROOM module with fixed 3.3V power?

Thanks!

Thanks

OK, I checked the documents but I afraid there is not what I' looking for. There are a lot of schematics showing what is inside the ESP-WROOM-32 module, but I could not find any information what the minimum required wiring is when using this module!

So for sure I need to connect GND and +3.3V

How about EN? Any other signals that are mandatory and need to be connected?

What do I need to program it from outside - which serial interface is responsible from that?

Thanks!

Try this

Hi Mike, page 15 of the ESP32-WROOM-32D module, you can find the peripheral schematic https://www.espressif.com/sites/default ... eet_en.pdf
The version D is recommended by Espressif for new designs. Cheers!

Great - Thanks!
