Badger 2040 W e-Paper display gets WiFi & Bluetooth with Raspberry Pi Pico W

Badger RP2040 W

Pimoroni Badger 2040 W wireless programmable e-Paper badge comes with a 2.9-inch black & white E-Ink display and a Raspberry Pi Pico W board for WiFi (and Bluetooth) connectivity. It is an update to the Pimoroni Badger 2040 with the exact same display, but instead of using a Raspberry Pi RP2040 microcontroller, Pimoroni fitted a Raspberry Pi Pico W on the back of the board, probably to avoid going through FCC and CE certifications. Badger 2040 W specifications: MCU board – Raspberry Pi Pico W board with: Raspberry Pi RP2040 dual-core Arm Cortex M0+ running at up to 133Mhz with 264kB of SRAM Storage – 2MB QSPI flash Wireless  – 802.11b/g/n WiFi 4 and Bluetooth Classic+LE with ABRACON onboard antenna (Infineon CYW43439 connected over SPI) Display – 2.9-inch B&W E-Ink display with 296 x 128 pixels resolution, ultrawide viewing angles, ultra-low power consumption; Dot pitch – 0.227 x 0.226 mm […]

Merlot is an open-source hardware tricolor wireless E-paper display

paperd.ink Merlot is a tricolor E-paper display with an open-source hardware control board based on ESP32 wireless SoC that is programmable with Arduino, MicroPython, or the ESP-IDF framework. We first wrote about the paperd.ink 4.2-inch ESP32-based monochrome e-Paper display last year, but the company has now refined its design with the “paperd.ink Classic” replacing the 3D printed enclosure with a vacuum cast enclosure and adding a 1,900 mAh battery. They also launched a new model, the Merlot, based on the same design but with a display supporting three colors: black, white, and red. Merlot 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″ tricolor e-Paper display with 400 x 300 resolution; full refresh: ~ 17 seconds; partial update: also 17 seconds… USB – 1x […]

Inkplate 2 is a 2.13-inch WiFi ePaper display programmable with Arduino or MicroPython (Crowdfunding)

Inkplate 2 wireless ePaper display is by far the smallest display from Soldered Electronics with a 2.13-inch 3-color ePaper display while previous Inkplate models rely on 6-inch to 9.7-inch ePaper displays. The tiny display board integrates an ESP32 dual-core wireless microcontroller that drives the display, provides WiFi and Bluetooth connectivity plus some I/Os, and can be programmed with the Arduino IDE or MicroPython. Inkplate 2 specifications: Wireless module – ESP32-WROVER-E module with ESP32 dual-core microcontroller with Wi-Fi 4 & Bluetooth 4.0 connectivity, 8MB PSRAM, 4MB flash (Note: The product’s description lists 8MB flash, and 4MB RAM, but there’s no ESP32-WROVER-E in this configuration) Antenna- External IPX antenna Display – 2.13-inch ePaper display with 212×104 resolution (111 DPI) Red, black, and white colors 15 seconds full refresh time (no partial update) USB – 1x USB Type-C port for power and programming via CH340 USB to TLL chip Expansion 20-pin header with […]

$52 7.5-inch E-paper display connects to ESP32 boards

So far LILYGO’s ESP32 boards with an E-Paper display such as the TTGO T5  or Mini E-Paper Core featured smaller displays from 1.02-inch to 2.9-inch. But the company is now offering a larger 7.5-inch display that works with most of its T5 boards excluding the one used with a 4.7-inch display. The black and white e-paper display offers a resolution of 800 x 480 pixels, is Arduino programmable and backward compatible with earlier T5 E-paper solution, and should be one of the most cost-effective to way to make a wireless E-paper display. LilyGO 7.5-inch E-paper display specifications: Panel SKU – DKE DEPG0750_U790F3 (See PDF datasheet. note non-secure link so your browser may complain) Size – 7.5-inch diagonal Resolution – 800 x 480 pixels (124 DPI) Active area – 163.2 x 97.92mm Pixel pitch – 0.204 x 0.204 mm Host interface – SPI Dimensions – 170.2 x 111.2 x 1.2 mm […]

$150 InkPalm Plus eReader features RK3566 SoC, 5.84-inch display

Xiaomi Moaan InkPalm Plus is a 5.84-inch eReader powered by the same Rockchip RK3566 processor found in Pine64 PineNote 10.3-inch Linux eReader, and currently selling for 999 CNY, or about $150 US, on JD.com after a 100 CNY discount. The device looks more like a smartphone than an eReader with its relatively small display, but there must be demand for this type of hardware since it succeeds the earlier InkPlam 5 eReader with Allwinner B300 quad-core Cortex-A7 SoC, plus an even smaller 5.2-inch display. Inkpalm Plus specifications: SoC – Rockchip RK3566 quad-core A55 processor @ 1.8 GHz with Arm Mali-G52 EE GPU, 0.8 TOPS NPU (AI accelerator) System Memory – 2GB RAM Storage – 64GB eMMC flash Display – 5.84-inch E Ink display with 1440×720 resolution (276 PPI), front light with 24 levels and adjustable color adjustment, 5-point capacitive touch Audio – Mono microphone Connectivity – Dual-band 802.11b/g/n/ac WiFi 5, […]

E Ink Gallery 3 color ePaper offers faster refresh rate, higher resolution

This is confusing. E Ink just announced the Kaleido 3 color e-paper at the beginning of the month, and now comes up with E Ink Gallery 3 color e-paper. Before we try to look into the differences, let’s see what E Ink says about the new Gallery 3 color ePaper technology. Designed for the eReader and eNote markets, E Ink Gallery 3 is based on the E Ink ACeP  (Advanced Color ePaper) with a full-color gamut achieved through a four-particle ink system: cyan, magenta, yellow and white, which allows a full-color gamut at each pixel. The earlier E Ink Gallery has a black and white update time of two seconds, and color updates of ten seconds. The new Gallery 3 ePaper technology slashes those times to 350ms for black and white and as low as 500 ms in fast color mode. The standard and best color modes have refresh rates […]
