Cardputer with M5StampS3 v1.1 Development Kit

Card-Sized ESP32 Development Platform for Connected Projects

The Cardputer with M5StampS3 v1.1 Development Kit is a compact, Wi‑Fi and Bluetooth‑enabled development platform designed for practical prototyping, IoT experiments, and STEM education. Built around the ESP32‑S3 dual‑core processor and the M5StampS3 v1.1 module, it combines processing power, connectivity, and rich I/O in a portable card-style form factor that fits easily in a pocket or small project enclosure.

The Cardputer integrates a dual-core ESP32‑S3 for responsive multitasking and smooth handling of interactive applications. Onboard Wi‑Fi and Bluetooth (via the ESP32) allow you to connect to networks, cloud services, and nearby devices for remote monitoring, control, and data logging. A HY2.0‑4P interface provides straightforward expansion for I2C sensors and modules, while the Micro SD card slot supports local data storage, logging, or configuration files. For human-device interaction, the unit includes an infrared emitter for IR remote control scenarios and a built‑in speaker suitable for basic audio feedback, alerts, or simple voice-related applications.

The M5StampS3 v1.1 core brings additional sensing and control capabilities, including a 6‑axis IMU for motion and orientation detection, a microphone for audio input and sound-based triggers, and a programmable key for custom user input. A Type‑C interface handles both power and code uploading, simplifying development workflows. The magnetic programming port and Lego‑compatible mounting holes make it easy to integrate the Cardputer into prototypes, classroom setups, or DIY enclosures. With dimensions of approximately 84 × 54 × 17 mm, it is well-suited for handheld tools, compact dashboards, and mobile IoT nodes.
