Fast Refresh 2.9 inch E Ink ePaper display with 296×128 resolution, four Grayscale, SPI interface, supporting partial refresh. Due to the bi-stable, the image once updated can stay on the display even when power is completely disconnected. The image is also high contrast and readable under sun just like printed paper. It is a perfect match for appliances like e-shelf label, smart tag, smart home application, pressure gauge and other industrial instrument panels.
Note: This price includes 5 pcs of 2.9inch epaper GDEY029T94 , 5 pcs of 24pin FPC connectors.
Since E-paper display is a new thing to many people they may ask what exactly it can be used for.
Here are just some cases but we super-look forward to seeing YOU to excel and develop this tiny gadet beyond our imagination.

SUCCESSFUL APPLICATION BY OUR CLIENT
Product Name: Wireless mini weather station + 2.9-inch e-paper
What is it?
It is a compact wireless mini weather station with a 2.9 Inch e-paper display with screen resolution of 296×128 pixels. The device has an industrial look, at least I wanted to achieve this. The sensor has very good energy efficiency. Powered by nRF52 multi-protocol chip (BLE, Zigbee, Thread, ESB). The device comes preinstalled with MySensor Protocol (ESB) wireless networking software – www.mysensors.org, can also work as a standalone device without a network. Can use both a ready-made device and a device for developing your own software right away.
What makes it special?
RF module MINEW MS50SFA supplied in several modifications with nRF52810, nRF52811, nRF52832 chips or RF module EBYTE E73-2G4M08S1C with nRF52840 chip.
Arduino development environment compatible.
The project uses e-paper display (GDEH029A1) from Dalian Good Display Co.ltd.
Very long runtime with one or two CR2450 battery.
Operation with CR2430, CR2450, CR2477 batteries (300mA – 1900mA) OR 2 AAA battery(extended version).
Several versions of the device, in the extended version is available: Ambient Light Sensor MAX44009 (+1μA), Active Buzzer.
Consumption in data transmission mode – 8mA, in sleep mode 4.7μA.
The ability to install different sensors (si7020, si7021, sht20, sht21, htu20d, htu21d or bme280(sold with this sensor))
The case is printed on a FDM or SLA 3D printer, For FDM printing, PLA Carbon Black(оnly this option is on sale), PLA Wood or PLA White is used, and for SLA printing, white or black resin is used. After printing, sanding and polishing is applied
Inside the case, magnet are installed for fixing to magnetic surfaces.
!!!Now there is an increase in prices for electronic components, for example, the bme280 sensor rose in price by more than 100% in March 2021.!!!
