Description

With the 2.9″ ESPaper module you can display data retrieved over WiFi on an ePaper with little effort. The integrated ESP8266 Wroom-02 module updates the 296×128 B&W ePaper display over the SPI bus. The module also features a charging circuit for LiPo batteries and a JST connector which allows you to run the module for weeks or even months from a battery. How long the module can be run from battery mostly depends on the update frequency and the battery capacity. In tests we could run the module from a 800mAh LiPo battery for several weeks by updating weather information every 20 minutes.

The open sourced Minigrafx is available on Github and provides a driver and examples to get quickly started with programming the module. We also provide a WeatherStation sample app which lets you get started quickly

Features:

  • 2.9″ ePaper module 296*128 pixels, B&W

    • S0 FLASH/GPIO0: used to put ESP8266 in programming mode or for user menu
    • S1 GPIO 12: User interaction

Please note: for programming the module you need a separate USB-to-Serial converter which supports 3.3V. This module is compatible with the kit: Serial-To-USB-Converter on Banggood
