Description:ESP8266 WeMos D1 Mini Lithium Battery Shield is a WeMos lithium battery shield board that is developed by WEMOS Electronic developer compatible with any ESP8266 D1 boards. This shield is a peripheral board that can add a lithium battery to the ESP8266 boards. This lithium battery can supply WeMos mini or WeMos mini Pro from a single cell (3.7V) lithium battery. This board is like an adapter that converts 3.7V DC battry voltage to a 5V DC voltage for supplying the WeMos mini and shields by the lithium battery power. This battery shield is equipped with an internal charging circuit to charge the batteries from a USB port of PCS, mobile charger, power bank, and so on. Also, it has an LED indicator for showing the full charge status.The ESP8266 series module is based on an ESP8266 WiFi module and one and more peripheral board. The ESP8266 boards are WIFI Arduino shield boards with a 160MHz, 32bit self processor and TCP/IP protocol, that can add Wi-Fi communication capability to the Arduino and microcontroller boards and also supporting the APSD and VOIP protocol. The ESP8266 module has enough processing capability and storage to be added with other simple boards with at least expansion up-front and minimum loading during runtime. The ESP8266 development board is interfaced with other boards through the I2C, UART, and SPI serial communication protocol. Communication with ESP8266 and its configuration is performed through the "AT Command" instructions. The ESP8266 can incorporate with another simple usual board such as this micro switchboard, the sensor boards, driver boards, and so on, to add WIFI capability to these boards. So all the ESP8266 boards have uniform interfaces includes GPIO, I2C, UART, and SPI serial communication header pins.
