Cardputer v1.1

SKU:K132-V11

Description

Cardputer v1.1 is a high-performance card computer designed for engineers, comprehensively upgraded from the original Cardputer. The new version features an all-new StampS3A microcontroller and optimized core module antenna and keys, significantly enhancing system stability and user experience.
In terms of control and interaction, the product is equipped with a 56-key keyboard and a 1.14-inch TFT screen for efficient display and operation; the onboard SPM1423 digital MEMS microphone supports recording and wake-up functions and outputs audio via an integrated cavity speaker; additionally, an infrared emitter provides external infrared control capabilities.
For expanded functionality, a built-in Grove interface facilitates custom sensor expansion; storage is enhanced with a Micro SD card slot for easy expansion of storage space. The power system employs an internal 120mAh battery alongside a 1400mAh battery in the base, integrating lithium battery charging and boost/buck circuits to greatly extend battery life. Structurally, the base is equipped with magnets for metal adhesion and is compatible with LEGO stud expansion.
This product is widely applicable for rapid functional verification, industrial control, home control systems, and various other application scenarios.
