Stamp-S3

SKU:S007

Description

Stamp-S3 is a highly integrated embedded core module based on the Espressif ESP32-S3FN8 SoC with 8 MB SPI flash. It features a high-performance 32-bit Xtensa LX7 dual-core processor running at up to 240 MHz and integrates a 5 V-to-3.3 V power circuit, an RGB status LED, and a programmable button.
The module exposes 23 GPIO pins of the ESP32-S3 on both 1.27 mm and 2.54 mm pitch headers, supporting multiple mounting options such as SMT, DIP male header, DIP female header, and fly-wire.
With its compact size, powerful performance, rich IO resources, and low-power consumption, the module is ideal for embedded IoT controller applications.
