Description
WiFi ePaper display module
The 2.9″ ESPaper module displays data retrieved over WiFi on an ePaper display. The integrated ESP8266 Wroom-02 module updates the 296×128 black & which ePaper display over the SPI bus. The module also features a charging circuit for LiPo batteries and a JST connector. The passive nature of ePaper allows the module to run for weeks or even months from a battery on a single charge. Update frequency is almost exactly (inversely) proportional to total uptime. Tests showed a total uptime of several weeks for an update interval of 20 minutes.
ThingPulse also provides a WeatherStation sample application to be loaded onto this WiFi ePaper display kit. The application only requires a handful of parameters and is ready to go.

The open-source Minigrafx display driver library is also developed and maintained by ThingPulse. It offers examples for programming custom applications quickly.
