1. This develop board integrates ESP8266 with a 18650 Li-ion battery charging system (the battery is not included). 2. A standard 3000mAH 18650 Li-ion battery can run it for 17 hours. 3. It is easier to develop ESP8266 projects with a power bank. 4. LED indicator inside, clear to see the battery (green means full while red means charging). 5. Convenient to operate with a power switch and a sleep mode connector. 6. Protects your devices from overcharge and over discharge with 0.5A charging current and 1A output. 7. 10 digital pins support many functions: write / read / interrupt / PWM / I2C (except D0). 8. Note: If you put the wrong direction of battery, the charging chip will be destroyed.

Setup Guide

1
Identify the pins
Locate VCC (power), GND (ground), and data pins (SDA/SCL for I2C, MOSI/MISO for SPI, or TX/RX for UART). Refer to the pinout diagram on the product page.
2
Wire to your microcontroller
Connect VCC to 3.3V or 5V (check the module spec), GND to GND, and data pins to the appropriate GPIO pins on your Arduino or Raspberry Pi.
3
Install libraries
In Arduino IDE, go to Sketch → Include Library → Manage Libraries and search for the sensor library. Install the recommended version.
4
Upload example sketch
Open File → Examples → [library name] → Basic Example. Upload to your board and open Serial Monitor to view output.
5
Calibrate if needed
Some sensors (temperature, humidity, distance) may need a short warm-up period or calibration. Run the calibration sketch if provided.
