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.

    M5Stamp ESP32S3 Module

    It does everything you want, but not well!

    This is by far the best ESP32 you can buy. It is very capable, and easy to use if you program with Arduino or can be pretty challenging if you use the ESP-idf. great, small device that can be soldered directly to a board or use breadboard pins. Love that it has touch sensors all on one side. This brings me to it is still an ESP32, so if you're expecting high-reliability or completely free of random quirks, look at the Teensy. I do recommend this, if you want an esp32.

    Very compact ESP32S3 board

    Great compact board with good protection

    M5Stamp ESP32S3 First Impression - Wow

    For a compact and versatile little device this M5Stamp is amazing and unbelievably fast; dual processors allow for simultaneous exection of disparate code allowing the device to handle multiple functions like exposing a HTTP/HTML page and then executing tasks based on the responses from the URL.. Wow, lots of power and simply an amazing device. The only think I would ask of M5 is to include an RTC in all their CPU boards as this is so critical to many applications...
    Buy one; the price is perfect for testing, prototyping or STEM work in academic locales... If you are like me, you will by 4 or 5 and proto with 1/2 devices and deploy on the remaining devices... Just amazing technology in such a small package..
