Integrated 2.4 GHz WiFi and lowpower Bluetooth LE provide efficiency wireless communication, simplifying setup and reducing module count. power operation up to 20 dBm with support for infrastructure BS Station modes, SoftAP, and Station+SoftAP, plus 1T1R modes delivering data rates up to 150 Mbps, enabling flexible network topologies and reliable connections. Centered around the ESP32S3R2 chip with a powerful Xtensa 32bit LX7 dualcore processor, capable of up to 240 MHz main frequency. Includes builtin onchip PSRAM of 512 KB, 384 KB, and 2 MB for fast memory access and responsiveness. ESP32S3 Development Board design features a USBA male port, a 1.14inch color LCD display, and a card slot, providing convenient I/O, realtime status visibility, and expandable storage for prototypes and projects. Compact development platform suitable for IoT gateways, edge devices, and rapid prototyping, combining wireless performance, flexible networking modes, and onboard peripherals in a single board. Use scenario 1: Build a wireless sensor gateway that provisions devices via SoftAP and maintains network connectivity through 2.4 GHz WiFi with BLE for peripheral sensors. Use scenario 2: Develop and test ESP32S3R2based applications that require a display and quick data logging, using the onboard LCD and card slot for status and storage. Use scenario 3: Create portable, demoready embedded solutions that benefit from USB connectivity, screen output, and flexible network configurations for demonstrations and field trials.
