paperd.ink 4.2-inch ESP32-based e-Paper display ships with a 3D printed enclosure (Crowdfunding)

paperd.ink ePaper Display

We’ve covered a fair amount of connected e-Paper/e-Ink displays based on ESP32 WiFi & Bluetooth SOC including several Inkplate displays, with the latest Inkplate 6Plus model including a touchscreen, TTGO T5 displays with small sizes, or even the fully enclosed M5Paper ESP32 IoT development kit with a 4.7-inch touchscreen e-Paper display. There’s also Watchy ESP32 smartwatch with a 1.54-inch display if you really need something small. But here’s another option courtesy of Rohit & Prasad, two young engineers from India, with the paperd.ink 4.2-inch ESP32-powered e-Paper display that ships with an optional 3D printed enclosure. paperd.ink display specifications: Wireless module – ESP32-WROOM-32 module with ESP32 dual-core processor, 4 MB SPI flash, 2.4 GHz WiFi 4 & Bluetooth LE connectivity Storage – MicroSD card slot for storing images, files, etc Display – 4.2″ monochrome e-Paper display with 400 x 300 resolution; 3s for full refresh; partial refresh supported USB – 1x […]

Inkplate 6PLUS ESP32 ePaper display gets higher resolution, a touchscreen, a frontlight (Crowdfunding)

Inkplate 6PLUS ESP32 wireless display

Inkplate 6PLUS is an updated version of Inkplate 6 ESP32 powered 6-inch ePaper display that was introduced in 2019, wand comes with a higher 1024 x 758 resolution, and the addition of a touchscreen and a frontlight. Just like the original product, Inkplate 6PLUS makes use of recycled e-paper displays without thousands of screens currently in stock. Refresh performance per pixel is faster and similar to Inkplate 10, which leads to a complete screen refresh being about as fast as on the original Inkplate 6 despite the higher resolution. Inkplate 6PLUS specifications: Wireless module – ESP32 WROVER module with dual-core ESP32 processor with Wi-Fi 4 & Bluetooth 4.0 (BLE) connectivity, 8MB PSRAM, 4MB flash External storage – MicroSD card socket Display  – 6-inch, 1024 x 758 e-paper display with support for grayscale, partial updates, and quick refresh cycles 1.27 second refresh time in black & white mode 1.52 second refresh […]

Tiny Tri-color E-Ink display for Wemos D1 Mini board sells for $10

tri color E-Ink display for Wemos-D1 mini ESP8266 board

Wemos D1 Mini is one of my favorites ESP8266 boards with a cheap price, tiny form factor, and support for stackable expansion boards. Lolin has now launched a small 2.13-inch tri-color E-Ink display that is compatible with D1 mini, D1 mini Pro, and D32 Pro boards, and sells for just $9.90 plus shipping. Specifications: 2.13-inchTri-Color (red/black/white) ePaper/e-Ink display with 212×104 resolution Driver IC – Good Display UC8151D Connection to D1 mini, D1 mini Pro, D32 Pro via 10-pin connector Debugging – 8-pin unpopulated header with EPD signals (SPI, Reset, Busy…) 3.3V, GND You may wonder why the PCB reads “2.13 INCH e-Paper 250×122”, while the resolution is 212×104. That’s because the company probably reused the PCB from their 2.13-inch black and white e-Paper display with 250×122 resolution (IL3897 driver). The display can be programmed with Arduino using LOLIN_EPD, Adafruit_GFX, and Adafruit_BusIO libraries as explained in the Wiki. You’ll find three […]
