Stamp-S3

SKU:S007

Description

Stamp-S3 is a highly integrated embedded main control core module. It uses the Espressif ESP32-S3FN8 main control chip, equipped with 8M SPI flash memory, and features a high-performance Xtensa 32-bit LX7 dual-core processor with a main frequency of up to 240MHz. It integrates a highly integrated 5V to 3.3V circuit, RGB status indicator, and programmable button. The module exposes 23 GPIOs from the ESP32-S3 and presents them in 1.27MM/2.54MM spacing, supporting SMT, DIP pin headers, DIP sockets, and flying leads for various usage scenarios.

This product is characterized by its compact size, powerful performance, rich expansion IOs, and low power consumption. This module is suitable for IoT applications requiring embedded main control modules.
