Wemos D1 mini Powerlevel? #402

Closed timtimsson closed 6 years ago

timtimsson commented 7 years ago

Hi, all my Wemos D1 mini have got a Powerlevel between Vcc 2,72-2,78. Is this correct or a little bit to low? Thanks

davidelang commented 7 years ago

that seems quite low to me.

arendst commented 7 years ago

Mine are low too. It looks to be normal for Wemos D1 mini.

... only for my understanding, if i have a level on tele from 2,7V on the sonoffLEDPanel, then breakdown the sonoff device?!) my measurement between the wemos pin are: GND-3.3=> 3.02V GND-5=> 4.47V where can i find the 2.7V? Thanks

timtimsson commented 7 years ago

ups, my ElectroDragon Module shows: 0.224V ?

Dive into the wonderfull world of esp8266 ADC and enjoy it's dynamic functionality...

On the Sonoff Led it provides a great means of comparing within it's family with functional (> 2.7V) and disfunctional. On the wemos I've never see any problems with ADC voltages of 2.7V

arendst commented 7 years ago

The ADC input on Sonoff is not connected.

The ADC input of the Wemos is connected with a 100k resistor to Gnd which will lower the ADC value considerably resulting in your findings.

The Electrodragon is worse by connecting the ADC with a 1k resistor to Gnd resulting in even lower values.
