ESP32-S3 Schematics
The ESP32-S3 is Espressif's dual-core Xtensa LX7 microcontroller with 2.4 GHz Wi-Fi and Bluetooth 5 (LE). It adds vector instructions for AI and signal-processing workloads, native USB OTG, and up to 45 programmable GPIOs, making it a popular choice for camera, display, voice, and other edge AI devices. Common modules and boards include the ESP32-S3-WROOM-1, ESP32-S3-MINI-1, ESP32-S3-DevKitC-1, and the Seeed Studio XIAO ESP32-S3. They are used in smart home controllers, wearables, HMI panels with SPI or RGB displays, and battery-powered IoT sensors. Flux.ai has a large community-driven public library of ESP32-S3 parts, modules, and reference designs, with footprints, symbols, datasheets, and 3D models, so you can drop the ESP32-S3 into a schematic and PCB and start designing right away.
