SKU:K132-V11






































Cardputer v1.1 is a high-performance card computer designed for engineers, offering a comprehensive upgrade over the original Cardputer. The new version adopts the brand new Stamp-S3A main controller, with optimized antenna and button design for the core module, significantly improving system stability and user operation experience.
In terms of control and interaction, it features a 56-key keyboard and a 1.14-inch TFT display for efficient operation and display; a built-in SPM1423 digital MEMS microphone supports recording and wake-up functions, while a cavity speaker outputs audio; an infrared emitter enables external infrared control interactions.
For expansion, the built-in Grove interface allows for custom sensor extensions; storage is supported via a Micro SD card slot for storage expansion. The power system consists of a built-in 120mAh battery and a 1400mAh base lithium battery, with integrated charging and power conversion circuits for greatly improved battery life. The base has an integrated magnet for metal surface attachment and is compatible with LEGO hole extensions.
This product is widely applicable to scenarios such as rapid function verification for engineers, industrial control, and home control systems.
