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 demonstrated in this tutorial 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 Electronic Shelf Label Firebase Edition V2.0 allows you to operate as many of them as you wish, provided that each has its own unique ID, and there's enough power and bandwidth for all of them.

An electronic shelf label (ESL) is a type of price tag. The one that enables you to easily set and update the product name, pricing, product description, etc.
The ESL that I've developed enables you to showcase up to 195 characters of relevant product information. It is comprised of only two components: ESP8266 and a 1.77-inch TFT LCD with ST7735.
As for the number of ESLs you can operate. Technically, this particular ESL allows you to operate as many of them as you wish, provided that each has its own unique ID, they all share the same cryptographic key, and there's enough power and bandwidth for all of them.
