RAK14000 E-Ink Display Module Datasheet
Overview
Description
The RAK14000 WisBlock E-Ink Display Module is designed to be part of a production-ready IoT solution in a modular way and must be combined with a WisBlock Core and a WisBlock Base module.
The RAK14000 module provides an interface to connect an E-Ink Display, which is known to be an extremely power-efficient display. The E-Ink Display is an Active Matrix Electrophoretic Display (AM EPD) module with 2.13 inches active area (212 × 104 pixels for White Black Version and 250 x 122 pixels for the White-Black-Red Version). It also allows you to connect a Three-Button Module, which can be used on a different application. All of this can be controlled through a WisBlock Core.
There are two versions of RAK14000 module for sale in the RAKwireless Store, the white-black display panel and white-black-red display panel version.
