Waveshare 4-inch E-ink Spectra 6 full-color e-paper display is designed for the Raspberry Pi

Waveshare 4 inch, spectra 6 color e paper display

Waveshare recently launched the 4-inch e-Paper HAT+(E), a E-Ink Spectra 6 full-color e-paper module designed to work with the Raspberry Pi using the HAT+ standard. This 600×400 pixel display includes E-Ink Spectra 6 technology and doesn’t have a backlight. The Spectra 6 allows for high contrast and color saturation whereas no backlight means the display consumes very low power. The device communicates using SPI and is compatible with various controller boards like Raspberry Pi and Arduino. These features make this device useful for places like supermarkets, unmanned stores, shelf levels, hospital wards, and more. Waveshare has launched various e-paper displays in the past including the EINK-DISP-103 E-paper HDMI Display, the 4.2″ and 7.5″  Waveshare NFC-powered e-Paper display, and most interestingly the 7-Color e-Paper Display. Feel free to check those out if you are looking for high-quality displays. Waveshare 4-inch spectra 6 color e-paper display specification Display – E-Ink Spectra 6 […]

Zerowriter Ink e-paper word processor

Zerowriter Ink is an e-paper word processor for writers interested in an open-source, distraction-free writing tool built around the ESP32-S3 wireless microcontroller. It features a customizable, mechanical keyboard with low-profile Kailh Choc switches and a second-edition Inkplate 5 e-paper display from Soldered Electronics. The Zerowriter Ink is a compact, dedicated writing tool that can be tossed in a backpack and taken on the road. It is designed as an open-source, customizable alternative to other portable word processors like the Alphasmart Neo and the Pomera DM30. It builds on the first ZeroWriter project but comes fully assembled. The keyboard is hot-swappable, with a US-English layout and printed legends. The onboard Inkplate 5 e-paper display is powered by an ESP32-S3 microcontroller with support for Wi-Fi 4 and BLE 4. It also comes with a 5,000mAh LiPo battery that can last for several weeks of daily use or a month of standby on […]

LILYGO Mini E-Paper Core IoT controller gets ESP32-S3 wireless microcontroller

LILYGO Mini E-Paper ESP32-S3

LILYGO Mini E-Paper Core has gotten an upgrade to the ESP32-S3 wireless microcontroller. The IoT controller was first introduced in 2021 with an ESP32-PICO-D4 system-in-package, a 1.02-inch E-Paper display, and a few GPIOs on the back, and the company kept the same design for the ESP32-S3 model called “Mini E-Paper Core S3”. The tiny ESP32-S3 IoT controller can still be used for integrated into your own project, and the company also provides several shields with nRF24L01 2.4GHz wireless or 433/868 MHz “LoRa” connectivity to transform the device into a longer range IoT device. Mini E-Paper Core S3 specifications Wireless SoC – Espressif Systems ESP32-S3FN4R2 CPU – Dual-core Tensilica LX7 @ up to 240 MHz with vector instructions for AI acceleration Memory – 512KB RAM, 2MB PSRAM Storage – 4MB flash Wireless – 2.4 GHz WiFi 4 and Bluetooth Storage – MicroSD card socket Display – 1.02-inch e-paper display with 128×80 […]
