M5StampS3A ESP32S3 Module

The M5StampS3A ESP32S3 module is a highly integrated embedded module based on the Espressif ESP32-S3FN8. It features a 240 MHz Xtensa LX7 dual-core processor and 8 MB flash memory. A programmable RGB LED and a user-friendly button make interaction easy. The optimized 3D antenna design improves wireless communication properties, allowing the module to operate reliably even in environments with high interference. In total, 23 GPIO pins are available, accessible via 1.27 mm or 2.54 mm SMT/DIP pin headers or sockets, enabling easy embedding into boards with limited space. The compact size of only 26 × 18 × 4.7 mm and a weight of around 3 g make it suitable for portable devices and industrial systems. The versatile input/output supports SMT, DIP, flat cable, or unit applications, enabling different casing and development forms. Developers can program the module with UiFlow2, the Arduino IDE, ESP-IDF, or PlatformIO. A supply voltage of 5 V, an energy-efficient dual-core processor, and an improved button design ensure high efficiency. Additionally, the SoC provides interfaces for touch sensors, SD/SDIO/MMC hosts, SPI, SDIO/SPI slave control, EMAC, motor PWM, LED PWM, UART, I²C, I²S, and counter inputs, allowing for the connection of extensive peripheral devices.
