5Stack Cardputer: A Versatile and Compact Development Platform

The M5Stack Cardputer is a remarkable card-sized portable computer that has been designed with engineers in mind, offering a powerful and feature-rich platform for a wide range of applications, from rapid functional verification to industrial control and home automation. At the heart of the Cardputer is the M5StampS3, a mini development board based on the ESP32-S3 chip, which provides a dual-core processor and supports Wi-Fi functionality, making it an ideal choice for a variety of projects.

One of the standout features of the Cardputer is its user-friendly interface, which includes a 56-key keyboard and a 1.14-inch TFT screen, allowing users to easily enter and view information. The on-board SPM1423 digital MEMS microphone and built-in speaker enable voice operations such as recording, wake-up, and audio playback, further enhancing the device’s versatility. Additionally, the infrared emitter enables users to interact with external devices such as TVs or air conditioners, making the Cardputer a valuable tool for home automation and control.

The Cardputer also offers a HY2.0-4P interface for expanding its capabilities by connecting various I2C sensors, such as temperature and humidity sensors, light sensors, and pressure sensors. This allows users to easily add different functional modules according to their needs, unleashing their creativity and customizing the device to suit their specific requirements. Furthermore, the Cardputer includes a Micro SD card slot, enabling users to store program code, data files, images, audio, and other resources, providing ample storage space for their projects.

To ensure long-lasting performance, the Cardputer is powered by a robust internal battery 120mAh+1400mAh (in the base) lithium battery. The device also features built-in battery charging and voltage regulation circuits, automatically adjusting the voltage and current to protect the battery and the device itself. The base of the Cardputer incorporates a magnet, allowing it to be conveniently attached to metal surfaces such as fridges or whiteboards, further enhancing its versatility and portability.
