What is it?

This is a custom Featherwing to connect Waveshare e-paper modules to Adafruit's HUZZAH 8266 and HUZZAH 32 Feathers. Features include:

• Featherwing board uses all through hole components
• Featherwing board can be built using just male headers or add buttons for more functionality
• Featherwing can either be soldered to be above or below the HUZZAH board.

Why did you make it?

Waveshare makes some great e-paper devices. Unfortunately, interfacing with Adafruit's Feathers requires soldering at least 8 wires (more if you need buttons). That is a lot of wires to solder in a small space. This Featherwing makes it much easier with only headers and buttons to solder. This Featherwing is compatible with Waveshare e-Paper modules (SPI interface), not the raw displays.

This Featherwing is shipped as a PCB board only, you will need to add your own headers and optional buttons, which can be found here. Some light hand sanding will need to be done to remove the "mouse bites" on the board from the fabrication process.

What makes it special?

This is an easy way to integrate a Waveshare e-paper display to your Adafruit HUZZAH ESP32 or ESP8266 project. With the e-Paper feature of holding its display when powered off and the ESP feature of powering down to conserve battery power, a project utilizing an e-paper display can run for weeks or even months on a single battery charge.

Note

This Featherwing has been successfully tested with 2 Waveshare displays, the 400x300, 4.2inch E-Ink display module and the 296x128, 2.9inch E-Ink display module, and with 2 Adafruit Feathers, the HUZZAH 32 and HUZZAH 8266. You will find more details using the e-paper Featherwing here
