Description

This board is an excellent platform for developing with the ESP32 SoC, a single chip solution that combines Bluetooth and 2.4 GHz Wi-Fi capabilities. Different than our other development board, this one includes a 2.13″, 2-Color e-Ink/e-Paper display that communicates with the ESP32 over SPI and has a resolution of 250×128 pixels. It also carries a micro SD card adapter for applications requiring additional storage space.

e-Paper/e-Ink is a display technology that mimics the appearance of ink on paper. Unlike conventional displays, e-Paper reflects light just like ordinary paper and is capable of holding text and images indefinitely, even without electricity.

Due to its ultra-low power consumption, wide viewing angle, and clarity of display (even without power), e-Paper is an ideal choice for applications such as labels, tags, badges, and others where fast refresh rates aren’t necessary. Some of the downsides of e-Paper technology are its relative high price and slow refresh rates—in the order of 2 seconds for a full page—compared to OLED displays. Though animations aren’t really possible, we can use e-Paper in displays for things that don’t change too fast, for instance, ambient temperature and other Weather Station measurements.

Features:

  • No backlight, keeps displaying last content for a long time even when powered down
  • Ultra-low power consumption, basically power is only required for refreshing
  • Resolution: 250×128 pixels
  • Size: 2.13″
  • Operating voltage: 3.3V
  • Interface: 3-wire SPI, 4-wire SPI
  • Display color: black, white
  • Grey level: 2
  • Refresh power: 26.4mW (typical)
  • Standby power: <0.017mW
  • Viewing angle: >170°
