Portable ESP32-S3 Card-Sized Development Computer With Keyboard, Display, Audio And Wireless Connectivity
The M5Stack K132-ADV Cardputer-Adv is a programmable card-sized development computer built around the Stamp-S3A core module with an ESP32-S3FN8 32-bit dual-core processor. It combines a 1.14-inch LCD with a 56-key keyboard, providing an integrated interface for programming, data entry, menu navigation, and interactive embedded applications. The ESP32-S3 platform provides 2.4 GHz Wi-Fi and Bluetooth 5 LE connectivity, making the board well-suited for portable IoT terminals, wireless controllers, rapid prototyping, and connected embedded systems.
Cardputer-Adv integrates audio, sensing, storage, and expansion hardware within a compact portable platform. It features an ES8311 audio codec, high-SNR MEMS microphone, NS4150B amplifier, 1 W speaker, 3.5 mm audio-output jack, BMI270 6-axis motion sensor, infrared emitter, and microSD card slot. A built-in 1750 mAh lithium battery supports portable operation, while the HY2.0-4P Grove port and EXT 2.54-14P expansion bus allow sensors and other peripherals to be connected. The magnetic rear base and LEGO-compatible mounting holes provide additional installation flexibility for prototyping, automation, and educational projects.
