Limited Quantity of the new ESP32-S2 multimedia and breadboard development boards from Espressif are in stock!


ESP32-S2-Kaluga-1

ESP32-S2 is new SOC from Espressif which is supposed to solve some issues with current ESP32 and ESP8266 SOC chips.

First issue S2 solves is the small number of GPIOs ESP32 has, specially if you want to use the Ethernet interface. ESP32-S2 comes with 37 GPIOs in nice 5x5mm QFN28 package. The SOC is single core 240Mhz processor with build in USB interface. The Bluetooth and Ethernet interfaces are removed.

Pricewise ESP32-S2 is cheaper than ESP32 but a bit more expensive than ESP8266.

ESP32-S2-WROOVER module comes with 2MB of RAM and 4MB of Flash and will be able to replace ESP8266 everywhere while having enough resources to run secure SSL connection.

Two development boards are available for ESP32-S2.

ESP32-S2-Saiola-1R is the low cost entry breadboard experimental board which includes ESP32-S2-WROVER module, USB programmer, RGB LED and couple of buttons.

It has all GPIOs exposed for experiments:
