7.5inch NFC-Powered HD e-Paper Eval Kit - set with 7.5" e-Paper display + NFC module

Description

Kit with a 7.5" e-Paper display with passive power supply via NFC and an NFC module based on the ST25R3911B chip and the STM32F103 microcontroller. The display is enclosed in a lightweight case that protects against mechanical damage. No batteries required, and the transfer of displayed data and power during transfer is possible thanks to the NFC technology.

The NFC module has a built-in microSD card slot, on which the user can store graphics and then send them to the display using wireless technology. It is also equipped with an OLED display, function buttons, a microUSB socket and a USB-UART converter.

The displayed image can be also sent using a mobile device with the NFC function (the manufacturer provides the module with an application enabling data transfer to the display in a simple and convenient way). Full documentation with examples of use is available on the product Wiki page.
