🚀 Cardputer v1.1 – Next-Gen Card Computer Cardputer v1.1 is a high-performance card computer designed for engineers, representing a comprehensive upgrade from its predecessor. This new iteration integrates an all-new StampS3A microcontroller, alongside optimized core module antenna and keys, significantly enhancing overall system stability and user experience. For precise control and intuitive interaction, the Cardputer v1.1 is equipped with a 56-key keyboard and a sharp 1.14-inch TFT screen for efficient display and operation. The onboard SPM1423 digital MEMS microphone supports recording and wake-up functions, with audio output via an integrated cavity speaker. Additionally, an infrared emitter provides external infrared control capabilities for diverse applications. Functionality is further expanded with a built-in Grove interface for custom sensor integration, and a Micro SD card slot for effortless storage expansion. The power system is robust, featuring an internal 120mAh battery complemented by a 1400mAh battery in the base. Integrated lithium battery charging and boost/buck circuits dramatically extend battery life. Structurally, the base includes magnets for metallic adhesion and is fully compatible with LEGO stud expansion, offering versatile mounting options. This product is highly versatile, ideal for rapid functional verification, industrial control, home automation systems, and numerous other embedded application scenarios.
