M5StampS3A with 1.27mm Header Pins

The M5StampS3A with 1.27mm Header Pins is an ESP32-S3FN8 module with a dual-core 240MHz processor, 8MB Flash, integrated RGB LED, user button, and optimised 3D antenna. It provides 23 GPIOs via a pre-soldered 1.27mm SMT header for compact PCB integration.

M5Stack M5StampS3A with 1.27mm Header Pins is a highly integrated embedded module based on the Espressif ESP32-S3FN8. It features a 240 MHz Xtensa® 32-bit LX7 dual-core processor, integrates 8 MB Flash, a programmable RGB LED, and a user button. The deeply optimized 3D antenna design delivers stronger wireless performance. Twenty-three GPIOs are broken out and a 1.27 mm-pitch SMT pin header is pre-soldered, providing an even smaller footprint for high-density PCB integration and enabling developers to build compact applications quickly.
