Wow, these preassembled ESP32 plus touchscreen boards are extremely cheap, and there are tons of them in all kinds of different form factors on Amazon. I didn't realize this kind of thing was so plentiful, this seems like a great way to bootstrap many kinds of electronics/IoT projects

Yeah ESP32 is an awesome rabbit hole. An esp32-c6, cheap yellow display, and a 3d printer and you can build some really interesting things.


Any commercial products using ESP?


Just look for ESP32 CYD - CYD stands for cheap yellow display. There are a lot of variants.

Here’s a list of just a few. They’re insanely popular not only because they’re just good to use, but also because they’re one of the cheaper FCC approved modules you can buy, which takes a lot of the pain out of bringing a product to market.


A lot of Shelly devices use ESP chips: https://www.shelly.com/ - And they are hackable!


You can find the fcc notices in manuals if you search on espressif’s module grantee code which is 2AC7Z. Espressif is extremely widely used.


Loads, you can usually tell if something is limited to 2.4Ghz only.

Cabled up an EVSE the other day and the brains of that was a ESP32 chip.


Yes, many. As a random example, see: https://www.servethehome.com/ubiquiti-flex-mini-2-5g-review-...

The last image on the page shows various chips in the switch, the top left is an ESP32.


Interesting, seems like they're just using it as a MCU? Specs don't mention anything wireless, and I don't see an antenna.


If you pick a smart device that has WiFi connectivity, then there's about a 50% chance that it has an ESP inside.


My "smart" resistive water heater uses an ESP for Wifi connectivity, so it can heat the water when the electricity prices are low for example.


(my older) LIFX bulbs have an Espressif MAC address, and I think LIFX has stated they're ESP32-based in the past


I think there are plenty using espressif chips. One of my robot vacuums (possibly the Neato?) certainly appeared to be.


AFAIK my humidifier uses an ESP32 chip.
