WeMos D1 Nodemcu Module 18650 Battery

WeMos D1 Nodemcu Module

The WeMos D1 Esp Wroom 02 Board is equipped with an ESP8266 Mini-WiFi Nodemcu Module and integrated 18650 battery, allowing for extended use with the included Sony 3000mah battery that can power it for up to 17 hours. No longer will you have to worry about constantly supplying additional power for your ESP8266 projects, as this compact board has got you covered.

The WeMos D1 Esp Wroom 02 Board can be powered by the Sony 3000mah 18650 battery for over 17 hours. The WeMos D1 Nodemcu Module includes an integrated charging system and Indication LEDs to make charging and operation effortless and simultaneous. The LEDs show green when fully charged and red when charging.

The given paragraph appears to be missing. Please provide the original paragraph so a rephrased version can be written.

This product does not come equipped with a 18650 battery. Incorrect insertion of the battery may damage the charging chip.

Kindly avoid burning the program while charging. If you choose to burn the program, remember to disconnect the battery and ensure that the switch is in ON position.

It is advisable to use a 5V 500mA charging charger instead of one with more than 5V 1A, as it may cause heating. However, please refrain from touching or carrying the charging chip during the process. The temperature of the charging chip may rise to about 60 degrees while charging, but there will be no heat during regular use, so it is safe to carry.

Warning! The TP 5410 charging tip will become damaged if the battery is inserted in reverse.

Characteristics of WeMos D1 Nodemcu Module:

• Inputs from a single AD.
• Inputs that utilize the Micro USB connector.
• The D0 programmable LED.
• The circuit for AUTO PROGRAM.
• The WeMos D1 Nodemcu Module is comparable to the ESP8266 (ESP-WROOM-02 With TELEC).
• The analog input, also known as AD, comes with a built-in dividing resistor that is equal to 220K minus the ADC value minus 100K, all connected to GND.
• The SOLDER terminal is designated for activating the SLEEP MODE feature.
• This product is compatible with both Arduino and NodeMCU.
• It is possible to both operate and charge simultaneously.
• The 18650 charging circuit is equipped with a TP5410 for 5V boosting.
• This device is equipped with built-in protections against both overcharging and over-discharging.
• When using the LED indicator, you will see a red light when the device is charging and a green light when it is fully charged.
• With a 3000 mA 18650 battery, you can achieve a runtime of over 17 hours.
• The system enables simultaneous charging and discharging of the integrated 18650 battery.
• The 18650 battery’s power can be controlled by a single switch.
• The D1 and D2 pins are each connected to OLED’s SDA and SCL, respectively.
• FLATH, RSET, D5, D6, and D7 each control one of the five buttons.
• The 5 digital pins have the ability to configure various functions separately, such as write, read, interrupt, PWM, I2C and one-wire support.
• With the integration of OLED and five buttons, development is even more convenient. Plus, there’s the added feature of a programmable LED that can be controlled through GPIO16 to display the running status and other functions of the 8266. Both Operation and NodeMCU remain consistent throughout.
• The design concept is inspired by the open source project NodeMCU. It features a development board that combines 18650 charging and discharging systems, along with protection for both processes. Additionally, an OLED screen and five directional buttons are incorporated for ease of development.
