ESP32-S3 PRO Development Board – ESP32-S3-WROOM-1 N16R8, 16MB Flash, 8MB PSRAM & MicroSD Support
The ESP32-S3 PRO Development Board is a high-performance embedded development platform built around the ESP32-S3-WROOM-1 N16R8 module. It combines powerful processing, Wi-Fi and Bluetooth LE connectivity with expanded interfaces for prototyping, IoT, automation, data acquisition, and embedded control applications.
Compared with conventional ESP32-S3 development boards, the PRO version provides additional features such as on-board current monitoring, MicroSD/TF card support, enhanced power regulation, and easy access to most GPIO pins through header connectors. This makes it particularly useful for projects requiring external sensors, displays, communication modules, motors, or other peripherals.
The integrated DC-DC converter and LDO regulators provide a stable power supply for the ESP32-S3 and connected modules, reducing the need for additional external power circuitry.
