The 8MB PSRAM also makes this AIoT development board useful for richer wireless applications.

As an ESP32-S3 development board, it is especially useful when a project needs the ESP32-S3-WROOM-1 module, stable USB flashing, and a compact Wi-Fi Bluetooth LE board for connected devices. For wireless sensors, smart controllers, and local automation nodes, this AIoT development board keeps hardware selection simple.

Features

• ESP32-S3-WROOM-1 module: the Waveshare ESP32-S3-DEV-KIT adopts an ESP32-S3-WROOM series module with dual-core 240MHz processing.
• Wireless development: this Wi-Fi Bluetooth LE board supports 2.4GHz Wi-Fi, Bluetooth LE, and Bluetooth Mesh application development.
• Flexible memory options: choose the 8MB Flash version or the 16MB Flash version, both with 8MB PSRAM for richer AIoT development board projects.
• USB Type-C development: onboard CH343 and CH334 chips support USB and UART development through the Type-C interface.
• Broad software support: the board works with ESP-IDF Arduino MicroPython, so firmware can be developed in the environment that best fits the project.
• Expandable pinout: the ESP32-S3 development board is compatible with the ESP32-S3-DevKitC-1 pinout and supports peripheral expansion.
• Carrier-board friendly: castellated module edges allow the module to be soldered directly to custom carrier boards.
