Title: ESP32 PoE 5V output
Post by: Karan on July 19, 2021, 10:58:04 AM
Hi All!

Does the ESP32-PoE have a 5V output to power peripherals when connected over battery and not over the PoE?

If not, does any other ESP32 board have a battery powered 5V output pin available?

Regards,
Karan

In short - if you need 5V, you would need either USB power or PoE power. I don't think we have ESP32 board with step-up converter from 3.7V to 5V.

When powered by 3.7V Li-Po battery, there is no 5V available on the ESP32-PoE board. ESP32-PoE has no step-up.

I can't think of an ESP32 board from our portfolio that has a step-up from 3.7V to 5V.
