The Card Computer: M5Stack card computer – OpenELAB
The M5Stack Cardputer is a compact, card-sized portable computer designed for engineers and developers. At its core lies the M5StampS3 , a mini development board based on the ESP32-S3 chip. Here are some key features of the Cardputer.
- Powerful Dual-Core Processor: The M5StampS3 features a dual-core processor, providing ample processing power.
- Wi-Fi Connectivity: It supports Wi-Fi functionality, allowing for wireless communication.
- BLE Connectivity: It supports Bluetooth Low Energy (BLE), and aims to provide considerably reduced power consumption compared to Classic Bluetooth while maintaining a similar communication range.
- Integrated Peripherals and Sensors: The Cardputer integrates various peripherals and sensors, making it ideal for rapid functional verification, industrial control, and home automation systems.
- User-Friendly Interface: It includes a 56-key keyboard and a 1.14-inch TFT screen for easy data entry and viewing.
- Voice Operations: With an onboard SPM1423 digital MEMS microphone and built-in speaker, voice operations like recording and audio playback are possible.
- Infrared Control Interaction: An infrared emitter enables interaction with external devices such as TVs or air conditioners.
- Expandability: The HY2.0-4P interface allows for connecting and expanding I2C sensors (e.g., temperature, humidity, light, and pressure sensors).
- Micro SD Card Slot: Users can expand storage space using the Micro SD card slot.
- Battery Life: Powered by an internal 120mAh+1400mAh lithium battery (in the base), the Cardputer eliminates battery life concerns.
- Magnetic Base: The base incorporates a magnet, allowing attachment to metal surfaces like fridges or whiteboards.
- Lego-Compatible Structure: Users can get creative by adding Lego bricks to the Cardputer’s structure.
Applications include fast functional verification, prototyping, industrial control, home automation, data acquisition, and embedded system development.
