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
- brcmthrowaway 8mo agoAny commercial products using ESP?
- bdavbdav 8mo agoI think there are plenty using espressif chips. One of my robot vacuums (possibly the Neato?) certainly appeared to be.
- saidinesh5 8mo agoJust look for ESP32 CYD - CYD stands for cheap yellow display. There are a lot of variants. https://github.com/witnessmenow/ESP32-Cheap-Yellow-Display?tab=readme-ov-file https://github.com/witnessmenow/ESP32-Cheap-Yellow-Display?t... . I bought mine for about $12 and it's been quite fun tinkering with it.

- shawnz 8mo agoAFAIK my humidifier uses an ESP32 chip.
- slmkbh 8mo agoA lot of Shelly devices use ESP chips: https://www.shelly.com/ https://www.shelly.com/ - And they are hackable!
- bri3d 8mo agohttps://templates.blakadder.com/esp32.html https://templates.blakadder.com/esp32.html 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.
- MallocVoidstar 8mo agoYes, many. As a random example, see: https://www.servethehome.com/ubiquiti-flex-mini-2-5g-review-ubiquiti-does-a-cheap-5-port-2-5gbe-switch/ 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.
- magicalhippo 8mo agoInteresting, seems like they're just using it as a MCU? Specs don't mention anything wireless, and I don't see an antenna.
- cyberax 8mo agoIf you pick a smart device that has WiFi connectivity, then there's about a 50% chance that it has an ESP inside.
- jansper39 8mo agoLoads, 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.
- magicalhippo 8mo agoMy "smart" resistive water heater uses an ESP for Wifi connectivity, so it can heat the water when the electricity prices are low for example.
- kurtoid 8mo ago(my older) LIFX bulbs have an Espressif MAC address, and I think LIFX has stated they're ESP32-based in the past
- buescher 8mo agoYou can find the fcc notices in manuals if you search on espressif’s module grantee code which is 2AC7Z. Espressif is extremely widely used.
- frogperson 8mo agoYeah ESP32 is an awesome rabbit hole. An esp32-c6, cheap yellow display, and a 3d printer and you can build some really interesting things.
