E-Paper Display Unit
Need a portable, low-energy, wireless display for the data you are collecting?
This display unit has an ESP32 Wi-Fi enabled micro-controller and a 2.13” e‑ink display, along with a nice wooden enclosure.
This kit is a simple, no-solder kit to get you up and running quickly.
It is designed for people who have some programming knowledge, as you will need to re-program the unit and make it do what you want.
When we saw this E-Ink development board, we loved it and started to make it display the data we wanted. We wanted it to look a bit more beautiful, though, so we designed a nice enclosure for it. We have also:
- Added a touch sensor wire with soldered terminal pad.
- Removed the power LED, as this ran the battery down too quickly!
Examples we have built for this display included:
- Weather display for your location. From Open Weather Map.
- Display data from Adafruit IO. In our case we display the radiation level in the workshop. Always useful!
- Quotation machine – need a boost? Touch the unit for an inspiring quote.
The limit is your imagination!
It displays the information even when the unit has gone to sleep, so is great for showing data or information that does not change too quickly.
You can set the unit to wake up on a touch, or to use the timer to wake it up at set intervals.
The kit includes a relatively simple wooden enclosure to hold everything and keep it at a nice display angle. We wanted something that would look nice on a mantle-piece!
It uses an 18650 lithium-ion cell, which is recharged via the micro USB connection. We have found a full battery to last for several hundred updates, but this does depend on your code.
Please note: The 18650 cell is not included, as we cannot easily ship them.

Note: This kit is based on the TTGO T5 V2.3 2.13 Inch E-Paper Screen. This is available here:
