Olimex ESP32-S2-DevKit-Lipo-USB-EA

Olimex ESP32-S2 development board with USB host and device functionality USB-OTG.

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 ESP32, ESP32-S2 is only single core and miss the Ethernet and Bluetooth connectivity, but have much mode GPIOs which were missing in ESP32.

The typical use is for WiFi enabled devices. ESP32-S2 supports low power modes including deep sleep that goes as low as 20uA.

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

ESP32-S2-DevKit-Lipo-USB uses the build-in USB interface and can work as host and device, even when powered by the LiPo battery.

All components used are with industrial grade oprating temperature -40 to 85°C. 

ESP32-S2-DevKit-Lipo-USB-EA comes with ESP32-S2-WROOM module with U.FL connector and external antenna attached.
