ESP32-S3 Development Board (ESP32-S3R2) Why this board solves real project problems Powerful processing for responsive applications: Dual-core Xtensa 32-bit LX7 running up to 240 MHz provides headroom for real-time control, UI tasks, and network handling without lag. Smooth wireless connectivity: Integrated 2.4 GHz Wi‑Fi and energy-efficient Bluetooth LE let you connect sensors, phones, and cloud services reliably while conserving power. Built for compact prototypes: The board combines a unique USB-A connector, a 1.14" color LCD, and a card slot so you can build interactive, expandable devices without many add-ons. Key features and benefits High-performance CPU: Xtensa 32-bit LX7 dual-core processor, up to 240 MHz—enables multitasking and faster computation for control, data formatting, and networking. Flexible memory options: On-chip PSRAM available in 384 KB, 512 KB, and 2 MB variants to suit different application memory needs. Strong wireless output and modes: Supports high-power operation (20 dBm), infrastructure base-station mode, SoftAP, Station+SoftAP, and 1T1R configuration with data throughput up to 150 Mbps — ideal for robust local networks and access-point applications. Integrated peripherals on the board: Built-in 1.14" color LCD for local status, debugging, or simple user interfaces; card slot for storage expansion or data logging; unique USB-A connector for convenient power and programming. Low-power Bluetooth LE: Enables battery-friendly peripherals, device commissioning, or proximity-based features with minimal energy use. Compatibility and practical details Development-focused: Designed for rapid prototyping with common development toolchains that support ESP32-S3 chips. Compact form factor: Board integrates display and expansion slot to minimize external components and reduce assembly time for prototypes. Standards-compliant wireless: Uses widely supported 2.4 GHz Wi‑Fi and Bluetooth LE protocols for broad device and cloud compatibility. Typical use scenarios Portable sensor gateway: Use the integrated Wi‑Fi and Bluetooth LE to collect data from BLE sensors, display status on the 1.14" LCD, and store logs on a card for later upload. High transmit power and 150 Mbps throughput keep local communications reliable. Interactive control panel: Build a compact user interface with the color display and on-board controls for home automation, industrial controls, or lab equipment. The dual-core processor handles UI and background communications concurrently. Local access point or edge node: Deploy the board as a SoftAP or Station+SoftAP node to create a small, resilient local network for IoT devices, with 1T1R wireless and 20 dBm power for extended coverage.
