Which ESP32 module would you recommend for power measurement?

Postby akris11 » Wed Jun 28, 2017 4:12 am

I am looking for a ESP32 based module with scope for power measurement.
Would like to power up the ESP32 from a external power source and do some power analysis..

Which board do you guys recommend?

The best ones for power measurements are probably http://esp32.net/images/Espressif/ESP-T ... ard_V3.jpg, but i don't think they are available for sale anywhere.

WROVER-KIT v3 (identified by black solder mask and female camera header) has a 0 Ohm resistor between WROVER/WROOM module and VDD net, which can be desoldered or replaced with a shunt resistor for current measurement.

Thank you very much for the quick response.

I have ESP32-DevKitC module and it is measuring 2.3 mA in deep sleep.
Any pointers on how to debug further?

Thank you for quick response.

I have an ESP32-DevKitC module and deep sleep current is around 2.3 mA. Any pointers?
I will post the measurement pic soon..
