Design and Implementation of a smart small blackboard with an E-ink screen

A smart small blackboard with an e-ink screen is designed to replace the traditional family message board, which is used for communication. The display in this project adopts e-ink screen. Compared with ordinary LCD and LED, e-ink screens are some advantages: low power consumption, flicker-free, no radiation, ultra-thin and this product can connect with smart phone, send a message information to ink screen terminal to display the information in time and remind on time as a result. This product is suitable for families with children and the elderly. It is mainly composed of main control chip, wireless communication module, display EPD(electric paper) module and backup power supply module based on IEEE802.11b\g\n protocol and TCPIP module and backup power supply module based on IEEE802.11b\g\n protocol and TCP\IP protocol, with ESP8266 chip to achieve the data connection, so as to achieve the final effect. In addition, this product can also use wireless communication to obtain the time and weather of the day through WIFl for intelligent display, and increase the product content.
