StampS3

SKU:S007

Description

STAMPS3 is a highly integrated embedded controller designed for IoT applications. It utilizes the Espressif ESP32-S3FN8 main control chip and features 8MB of SPI flash memory. Powered by a high-performance Xtensa 32-bit LX7 dual-core processor, STAMPS3 delivers impressive processing power with a main frequency of up to 240MHz. This module is specifically designed to meet the demands of IoT projects that require embedded main control modules.

STAMPS3 comes equipped with a built-in highly integrated 5V to 3.3V circuit, ensuring stable power supply for reliable operation. It features an RGB status indicator and a programmable button for enhanced user control and visual feedback. The module conveniently leads out 23 GPIOs on the ESP32-S3, allowing for extensive expansion capabilities. The GPIOs are accessible through 1.27mm/2.54mm spacing leads, supporting various usage methods such as SMT, DIP row, and jump wire connections. STAMPS3 offers a compact form factor, delivering strong performance, rich expansion IO, and low power consumption.

STAMPS3 is the ideal choice for IoT application scenarios that require the integration of embedded controllers. Its compact volume and powerful features make it suitable for a wide range of projects, providing reliable performance and flexible expansion options.
