Olimex launched ESP32-S2-DevKit-Lipo-USB Development Board

ESP32-S2-DevKit-Lipo-USB is an ESP32-S2 based 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 high performance and a rich set of IO capabilities. Compared to ESP32, ESP32-S2 is only single-core and misses the Ethernet and Bluetooth connectivity, but have many mode GPIOs which were missing in ESP32. The typical use is for WiFi-enabled devices. ESP32-S2 supports low power modes including deep sleep with 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 ability to work on LiPo power when the external power supply is missing, allowing handheld applications. ESP32-S2-DevKit-Lipo-USB uses the built-in USB interface and can work as host and device, even when powered by the LiPo battery. All components used are with industrial-grade operating temperature -40+85C.ESP32-S2-DevKit-Lipo-EA comes with an ESP32 module with a U.FL connector and external antenna attached.\

ESP32-S2-WROVER-DevKit-Lipo comes with ESP32-WROVER-B module with 4MB Flash and 2MB PSRAM. The power consumption of ESP32-WROVER-DevKit-Lipo is 65 uA in deep sleep mode.

ESP32-S2-DevKit-Lipo-USB can be programmed via a built-in USB interface, but the board has provisions for external programmers like ESP-PROG to be used for code programming.
