M5StampS3A ESP32S3 Module

The M5StampS3A ESP32S3 Module is an ESP32-S3FN8 module with a dual-core 240MHz processor, 8MB Flash, integrated RGB LED, user button, and optimised 3D antenna. It offers 23 GPIOs via 1.27mm/2.54mm headers for flexible PCB integration.

The M5Stack M5StampS3A ESP32S3 Module is a highly integrated embedded module based on the Espressif ESP32-S3FN8. It is equipped with a 240 MHz Xtensa® 32-bit LX7 dual-core processor, integrates 8 MB Flash, a programmable RGB LED, and a user button. The deeply optimised 3D antenna design offers stronger wireless communication performance.

Twenty-three GPIOs are broken out and provided via 1.27 mm / 2.54 mm pitch SMT/DIP pin headers or sockets, allowing effortless PCB integration and enabling developers to build applications rapidly.
