WeMos lithium battery shield (ESP8266)

This WeMos shield can be used to run the microcontroller und other shields from a lithium battery. It also charges ist up if USB is connected.

Get the shield from here:
..and the WeMos from here:

Thanks. Your video made me realize the polarity on my my lipo battery was backwards. Works great now. here is some code to read the voltage

const int analogPin = A0; // Replace with the correct pin for your shield

void setup() {
Serial.begin(115200);
}

void loop() {
int sensorValue = analogRead(analogPin); // read the input on the analog pin
float voltage = sensorValue * (3.3 / 1023.0); // Convert the analog reading to voltage
Serial.print("Battery Voltage: ");
Serial.print(voltage);
Serial.println(" V");
delay(1000); // Delay in between reads for stability
}

Using a pair of Dupont connector wires for the battery connection is brilliant! I thought I would have to de-solder the connector and solder on wires just to do my breadboard testing...

Did you get the chance to test the minimal power consumption with this shield while the WeMos is sleeping?

I connected a 3.7v lipo, and it started smoking...
(the small resistor 102 right next to the leds was smoking hot (0.7A))
Why did that happen?

nice video! so have you figured what battery actually has that type of connector?

Hi, gibt es einen link für den verwendeten Akku Pack?
Danke

In my project i need to monitor is powered by usb, or by battery now. If i use this shield, can i know get this data on controller pin ?

I know it's an old video, but what if the marker that you use befeore soldering?

Hallo, hier sind die Steckverbinder für das Shield bei Ali Express
