THE CURIOUS ELECTRIC TTGO E-Paper Display Unit

PRODUCT INFORMATION

• Date : 5/7/2022
• Version : 1.1
• By: Matt Little

Need a portable, low-energy, wireless display for the data you are collecting?
This display unit has an ESP32 Wi-Fi-enabled microcontroller and a 2.13” e-ink display. This kit is a simple, no-solder unit 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. These instructions cover the Standard version of this kit.

The kit is based on the TTGO T5 V2.3 2.13 Inch E-Paper Screen. This is available here: http://www.lilygo.cn/products.aspx And a GitHub repository for their info and notes is here: https://github.com/Xinyuan-LilyGO/T5-Ink-Screen-Series

We loved this little board and started to make it display the data we wanted. Examples we have built included:

• Weather display for your location
• Display data from Adafruit In our case we display the radiation level in the workshop. Always useful!
• Quotation machine – need a boost? Touch the unit for an inspiring 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 regularly. 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 mantelpiece! 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. The GitHub repository for example code and the enclosure and these instruction files is available here: https://github.com/re- innovation/TTGO_EPaper
