E-Paper Display hooked up with an ESP32 to Display various information such as weather, news, train departure, appointments and to-do lists. The ESP32 is programmed with Arduino IDE in C++.
I have been using this E-Paper display since the end of 2022 and it turned out genuinely useful. It helps me catch my train on time and I won't miss any important appointments.
- E-Paper Project
- ESP32 with SPI Interface (18,85€ @ amazon.de Stand: 04.11.23)
- E-Paper Display (54,90€ @ welectron.com Stand: 04.11.23)
- Housing for the E-Paper Display (5,90€ @ welectron.com Stand: 04.11.23)
- USB Extension Cable (5,99€ @ ebay.de Stand: 04.11.23)
- Soldering Iron
- Glue Gun
Here you can see the result mounted to the wall
In this picture, you can see the ESP32 and the E-Paper Display inside the Housing. The ESP32 is connected to the E-Paper Display via SPI. The ESP32 is powered by a USB cable which is connected to a USB power supply. The USB cable is routed through the housing and glued to the bottom of the housing so the USB cable is easily replaceable.
A part on how to configure this project is comming soon.
During this project, I encountered some difficulties.
| To solve this issue, I removed the chip and soldered a cable to the pins so that the chip is located next to the ESP. Now the ESP32 fits in the housing, great. |  |

I removed some plastic from the cable so it can fit in the housing.
