ESP32-S2 goes into Mass Production

If you have anything to do with electronics engineering, I am sure you must have already read about ESP Wireless SoC Chips.

What is ESP?

Espressif Shanghai, China based company launched their first WiFi chip ESP8266 and modules in year 2014 and then ESP32 (2016) popularly known for its dual core MCU and WiFi + Bluetooth combo on chip features.

Hundreds and thousands of engineers have already created several IoT products using ESP Chips. The biggest reason for such a wide adoption has been, its cost and the feature this wireless SoC provides. One can build a complete embedded system using the SoC or the module. The microcontroller inside is quite powerful, ESP8266 has 80Mhz MCU and ESP32 even has dual core MCU running at 240Mhz.

Do you know other option available in the market which offers such a high performance WiFi MCU with so many feature and at such an affordable price point? Please do share with me also.

What is new in ESP32 S2?

Espressif announced its new ESP32-S2 version chips a few months back and is now in mass production. For easy development, it comes with a few development board options. You can see on their website.

The spec is quite interesting, some parts are quite similar to what we have seen in the earlier ESP32 chip but a few new features are also introduced with this ESP32-S2 version chip.

Some of the notable differences are the following:

What is new or improved?

What is knocked off?

Pricing & from where to buy?

Other than local stores, Espressif chips, modules and kits are available on Mouser and Digikey. ESP32-S2 should be available in 1-2$ per unit on portals like LCSC, Aliexpress but will be a little higher on Mouser and Digikey.

ESP32-S2 will take some more time to come on these portals.


Hope you have enjoyed reading this article. I am very excited to try my hand on ESP32-S2 SoC based module and build an interesting project. What do you think?
