2.9″ ESPaper Lite Kit, WiFi ePaper display

(2 customer reviews)

$44.90

The 2.9″ ESPaper Lite Kit is the little sister of our fully assembled WiFi ePaper display kit. Weather station software is provided as a sample application. Thanks to the passive nature of the ePaper display it runs for months on a single charge. In order to program it you need an external USB-to-Serial converter which supports 3.3V. We recommend a Serial-To-USB-Converter from Banggood.

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.
