ESP32 Forum

An Electronic Shelf Label is a device that’s typically attached to the front edge of retail shelving. ESLs can be used to show relevant prices, product descriptions, and other information. One of the advantages of employing the ESLs instead of the traditional paper price tag is the ease of updating it. With ESL acting as a price tag, you no longer need to wander around the store searching for the right price tag on the right shelf, all you need to do is select the image that will be displayed on the ESL using the ESL management software.

To make things even better, the ESL that I developed doesn’t require an expensive gateway to function, once configured, all it needs is a power supply and a Wi-Fi access point (so it can get the image from the Google Firebase).

The tutorial for this ESL is available at:

Thanks a lot for sharing. I used this red display a couple of times but such an idea never came across my mind. It looks really beautiful.
