ESP32 E‑Paper Status Display

Using an ESP-32 board with an embed­ded E‑Paper dis­play, I cre­at­ed a gad­get that shows sta­tus infor­ma­tion from my web serv­er.

E‑Paper, also known as E‑Ink, only needs pow­er when being updat­ed, and uses no pow­er between updates. This means that the gad­get can be pow­ered for weeks from a recharge­able bat­tery.

The pur­pose of this gad­get is to put on my wall or desk, and show reg­u­lar­ly updat­ed impor­tant infor­ma­tion on my web serv­er, to keep informed of web site prob­lems and sta­tis­tics. The infor­ma­tion dis­played can be eas­i­ly changed, for exam­ple to the lat­est weath­er, news, cur­ren­cy prices or any­thing that can be accessed via the inter­net. E‑Paper means it uses a very small amount of pow­er and heat, com­pared to a com­put­er dis­play or tele­vi­sion.

You can view my code on GitHub if you are inter­est­ed in mak­ing your own.
