E-Paper driver to make your electronics smaller

Got from Waveshare some of this E-Paper ESP8266 driver boards:

I’m trying to make the electronics of my displays as small as possible and to avoid the wire-chaos inside the case with the goal of having more space for the battery. This will basically spare the need of the driver HAT and additional cables, something that is still present in my first prototype:

A bit messy uh ?

The only issue I see and I’m still sorting out with Waveshare is that the cable is not coming with the RAW display. But I think it will be not a show-stopper.

E-Paper ESP8266 driver board example developed by Waveshare

  • Supports Floyd-Steinberg dithering algorithm, more color combinations, better shadow rendering for the original image
  • Supports popular image formats: BMP, JPEG, GIF, PNG, etc.

Specifications

  • WiFi protocol: 802.11b/g/n
  • Interface: 3-wire SPI, 4-wire SPI (default)
  • Operating voltage: 5V
  • Operating current: 50mA ~ 100mA
  • Outline dimension: 29.57mm x 48.26mm
  • Mounting holes size: 2.9mm

When I find the time will post about the first tests and specially about consumption. Currently I’m using a 7.5 B/w only display with a 1200mA battery for our office. My only wish is that Waveshare electronics makes bigger E-paper displays so we can make more visible charts for our clients (10.3″ or 13 inches)

UPDATE from Waveshare

The sales people replied me, the cable is included when you buy the driver, it’s on Package contents Tab on Waveshare website:

  1. e-Paper ESP8266 Driver Board x1
  2. e-Paper Adapter x1
  3. 24PIN FFC x1
    1
    2+3-> 24 pins cable is included.
    So that’s it, you just need this driver, and to buy one RAW display. So it will run using a core of only 3 elements: Driver, Cable and E-paper display
