The ESP32-S2 is a highly integrated, low-power, single-core Wi-Fi Microcontroller SoC, designed to be secure and cost-effective, with a high performance and a rich set of IO capabilities.

Compared to the ESP32, the ESP32-S2 is only single core and misses the Ethernet and Bluetooth connectivity, but has many more GPIOs which were missing in the ESP32. The typical use is for WiFi enabled devices. ESP32-S2 supports low power modes including deep sleep that goes as low as 20uA.

The Olimex ESP32-S2-DevKit-Lipo-USB board is pin-to-pin compatible with Espressif ESP32-Saola-1, but adds a LiPo battery charger and the ability to work on LiPo power when external power supply goes missing, allowing handheld applications and increasing availability and reliability.

The board uses the built-in MicroUSB interface and can work as host and device, even when powered by the Li-Po battery (be sure to grab a micro-USB cable as one isn't included).

All components used are with industrial grade operating temperature -40+85C.

This version is the ESP32-S2-WROVER-DevKit-LiPo-USB, which comes with an ESP32-S2-WROVER module with 4MB Flash and 2MB PSRAM. Power consumption of the ESP32-WROVER-DevKit-Lipo is 65 uA in deep sleep mode.
