A cardputer is a card-sized portable computer that is perfect for engineers. At the heart of the M5Stack K132-Adv Cardputer Adv Version with ESP32-S3, a mini development board based on the ESP32-S3 chip. The Cardputer features a powerful dual-core processor, supports Wi-Fi functionality, and integrates various peripherals and sensors, making it ideal for rapid functional verification, industrial control, and home automation systems. The 56-key keyboard and 1.14" LCD display allow users to easily enter and view information. The onboard ES8311 codec, a precision MEMS microphone and built-in speaker enable voice operations such as recording, wake-up, and audio playback. The infrared emitter allows infrared control interaction with external devices such as TVs or air conditioners. Cardputer offers a HY2.0-4P Grove connectors and EXT 2.54-14P expansion headers, allowing for easy integration of external sensors and accessories, which allows users to add different functional modules according to their needs and unleash their creativity. The Cardputer also includes a Micro SD card slot for expanding storage space. Users can store program code, data files, images, audio, and other resources on the Micro SD card. The device is powered by an internal 1750mAh lithium battery lithium battery solution, eliminating concerns about battery life. In addition, the Cardputer has built-in battery charging and voltage regulation circuits that automatically adjust voltage and current to protect the battery and the device. The base of the Carputer incorporates a magnet, allowing it to be attached to metal surfaces such as fridges or whiteboards. What’s more, Cardputer's structure is compatible with Lego hole extensions, allowing users to create even more interesting designs using Lego bricks. Applications: Fast functional verification and prototyping Industrial control and automation Home Control System Data acquisition and sensor monitoring Embedded system development and learning Wireless communication and Internet of Things (IoT) projects Features: Stamp-S3A module with ESP32-S3FN8 core processor. 56-key keyboard. 1.14 Inch LCD display. Infrared emission distance Infrared emission distance (linear distance) of ∠180°: 410cm Infrared emission distance of < 90° : 66cm Infrared emission distance of < 45° : 170cm Cavity speaker and ES8311 digital MEMS microphone. Infrared emission tube is used for infrared control interaction. HY2.0-4P Grove connectors and EXT 2.54-14P expansion headers. Micro SD card slot for expanding storage space. The built-in 1750mAh lithium battery in the base provide long battery life. Base with magnet, compatible with Lego hole expansion.
