M5Stack StampS3 ESP32-S3 Module

Description

M5Stack StampS3 ESP32-S3 Module is a compact controller board designed as a highly integrated embedded controller for compact devices, smart sensors, and connected nodes. Based on the StampS3 module architecture and the ESP32-S3FN8 chip, it combines Wi-Fi, onboard flash, GPIO breakout, a programmable RGB indicator, and a programmable button in one IoT controller module that is easy to use in SMT, DIP, or jumper-wire builds.

Features

• M5Stack StampS3 ESP32-S3 Module uses the ESP32-S3FN8 with 8MB flash.
• This compact board works as a small embedded controller for IoT builds.
• The StampS3 module includes a programmable RGB LED and a programmable button.
• It exposes 23 GPIOs through 1.27mm and 2.54mm pitch options.
• The board is a flexible IoT controller module for SMT, DIP, and jumper-wire assembly.
