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

HiPo batteryless NFC-powered 3.52-inch e-Paper display also comes with an SPI interface (Crowdfunding)

HiPo is a 3.52-inch black and white e-Paper Display that can be updated through NFC without the need for external power and offers an alternative to the 4.2-inch and 7.5-inch NFC-powered e-Paper displays from Wareshare that also operate without battery only using the data and power from NFC to update the image. Alternatively, Guangdong SID Technology’s HiPo display can also be connected to an SPI adapter board allowing the users to connect it to an STM32 board provided by the company, but it could also be used with Arduino boards, ESP8266 & ESP32 hardware platforms, Raspberry Pi SBCs and MCU boards, or any platform with an SPI interface. HiPo specifications: Controller – Ultrachip UC8251 all-in-one driver IC with timing controller for E-tag applications Display 3.52-inch B&W e-Paper display with 360 x 240 resolution (model name: SE0352N01-MNG-A0) 3 seconds refresh time On-chip display RAM White reflectance above 30% Contrast ratio above […]

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

LILYGO 7-5 inch E-paper Display with T5 ESP32 board

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.
