Back in 2020, we wrote about Waveshare’s Batteryless NFC e-paper display, which can work without a battery and draws power and data from an NFC-enabled smartphone or the company’s ST25R3911B NFC board. Waveshare has now released a V2 version of this display with a new and improved NFC chip, a “fast flashing method”, and enhanced contrast. The new batteryless, 7.5-inch NFC-powered e-paper display features an 800×480 resolution and updates via an NFC-enabled smartphone or reader. It offers a 170° viewing angle and comes in a durable ABS plastic shell. The ST25R3911B NFC board allows updates via USB, SD card, or serial port, with an optional password lock. However, precise NFC positioning is required for updates.

These features make it ideal for shelf labels, equipment tags, and other applications. Waveshare 7.5-inch NFC e-paper display V2 specifications: In terms of software, the company mentions that this display has its own dedicated Android (NFTag) and iOS (NFC E-Tag) applications through which users can upload and manage images wirelessly via NFC. The Android app allows users to transfer images from NFC-enabled smartphones running Android 4.0 or later, though it is incompatible with Samsung and Google phones due to NFC limitations. The iOS application provides similar functionality for Apple devices. Users can customize displayed content with built-in image effects, including grayscale, block patterns, sketches, and more.

Users also have the option to upload images via NFC with the help of the Waveshares ST25R3911B NFC board via SD card or UART, adding flexibility for industrial and retail applications. The waveshare_epaper display platform allows you to use some E-Paper displays sold by Waveshare with ESPHome. The 2.13” TTGO module and the Waveshare Cloud Module with an ESP32 on the board are supported as well. Depending on your specific revision of the TTGO board you might need to try out the -b73 or -b1 version (see below). The 1.54” Good Display gdew0154m09 as used in the M5Stack Core Ink is also supported. Similar modules sold by other vendors might also work but not have been tested yet.

Currently, most displays managed by Esphome are single-color E-Ink displays; but Esphome also supports E-Ink displays capable of showing up to 7 colors. The communication ESPHome has chosen to use for this integration is 4-wire SPI, as it’s the most stable and high-speed. So you need to make sure your board is set to the 4-wire SPI mode and have an spi: section in your configuration. For the 7-color display, colors can be defined like this in the lambda function: cs_pin (Required, Pin Schema): The CS pin. low power, wide viewing angle, paper-like effect without electricity
