The duration of the is about 4-5 hours... I will find a source that can power it for 20 hours.

Can you advice me?

Hi,

I want to use an ESP32 with an external supply.

For the moment I used an alcaline battery 9v 600mAh, and run correctly. It' s enough? How long it can supply my circuit?

Someone have another advice for the external supply? I would like to use a battery as small as possible.

Thanks!

I have another question: for use te pin Vin for powered the esp32 it' necessary specified in the sketch or i just need power supply on that pin?

Ahh ok thank you very much!

Can you help me also for the connect? I see the datasheet but I don't understend where i must connect the power supply and where are the pin for seignal A and signal B

I want to use an encoder like this: https://www.amazon.it/gp/product/B01G78 ... UTF8&psc=1.

Can you recommend an encoder of a form similar to this but that maybe need 3 volt?

Hi,

I want to connect my Esp 32 to an external power supply like button battery, I also need to connect an encoder to the Esp32.
The problem is the encoder need 5volt of power supply.
Can you recommend the best soluction for me? The important is to use a tiny power supply.

Thanks,

Simone
