ESP32-S2 single core processor with 240 MHz and Wi-Fi connectivity (without Bluetooth)Print

Espressif released a new Wi-Fi IC called ESP32-S2, single core processor with frequency up to 240MHz, Wi-Fi connectivity 802.11 b/g/n (without Bluetooth) and with memory of 320 kB SRAM and 128 kB ROM.
ESP32-S2 completes the family of Wi-Fi connectivity ESP8266 and ESP32.
S2 version is not so powerful like the previous Wi-Fi IC ESP32, so the S2 version should be cheaper than ESP32.
ESP32-S2 should be used for the main purpose - secure Wi-Fi connection for communication with your server and cloud but cheaper than ESP32. ...
