This development board integrates ESP8266 18650 battery A standard 3000mah 18650 battery can run for 17 hours.It can be called "WiFi battery". I'm going to make it easier to develop ESP8266 ESP8266 projects by adding 18650 battery.When you do some ESP8266 projects you must hate to add power supply to provide power. This micro board can solve such problem. The 3000mah 18650 battery can run the ESP8266 for 17 hours or more.What makes it special?- Compatible with nodemcu.- 18650 charging system integration.- Indicator LED (green means full red means - charging) can be used while charging.- Switch to control the power supply.- SMT connector can be used for sleep mode - 1 additional LED programmable (gpio16)- 0.5a charging current- 1A output- Overcharge protection- Over-discharge protection- 10 digital pins for read/write/interrupt/PWM/I2C/line support (except D0)- Be careful with +- for analog inputs.
If the battery is in the wrong direction, the charging chip will be damaged.
The line layout is compact and regular, with good electrical insulation and mechanical stability, and can maintain stable performance under different temperature and humidity environments to ensure accuracy and reliability.
In circuit design, carefully planned lines are like precision transportation networks, and lines of different widths and spacings undertake different currents and signals transmission tasks respectively. The key signal lines are impedance matching processing, which greatly reduces signal reflection and attenuation and ensures the stable transmission of high-frequency signals.
All kinds of electronic components are soldered on the circuit board, and the solder joints are full, round, and firm and reliable. Core components like chips are perfectly connected to the circuit board through fine packaging processes to achieve high-speed data processing and interaction.
This circuit board has a wide range of responses in many fields. Whether in the industrial control field that requires extremely high stability or consumer electronics field that pursues extreme performance, it can provide solid guarantees for the stable operation of the equipment with its excellent design and reliable performance, and help various electronic devices play a powerful role.
