Description:Cardputer v1.1 is a high-performance card computer designed for engineers, offering a comprehensive upgrade over the original Cardputer. The new version features the brand new StampS3A main controller, with optimized antenna and button design for the core module, significantly enhancing system stability and user experience. In terms of control interaction, the product is equipped with a 56-key keyboard and a 1.14-inch TFT screen for efficient display and operation; it includes an onboard SPM1423 digital MEMS microphone supporting recording and wake-up functions, and outputs audio through a cavity speaker. Additionally, an infrared emitter provides external infrared control interaction capabilities. For expansion, the built-in Grove interface facilitates custom sensor expansion; for storage, a Micro SD card slot is available for easy storage expansion. The power system uses an internal 120mAh and a base 1400mAh lithium battery power solution, integrating lithium battery charging and boost-buck circuits, greatly enhancing battery life. Structurally, the base includes magnets for metal attachment and is compatible with LEG0 hole expansion. This product is widely applicable in various scenarios such as rapid function verification for engineers, industrial control, and home control systems.Features:StampS3A Microcontroller56-key keyboard1.14-inch TFT screenCavity speaker and SPM1423 digital MEMS microphoneInfrared emitter for infrared control interactionHY2.0-4P interfaceMicro SD card slotBuilt-in 120mAh and 1400mAh lithium battery in the baseBase with magnetsCompatible with LEG0 hole expansionDevelopment PlatformUiFlow2ArduinoIDEESP-IDFPlatformIOPackage Includes:1 x Cardputer V1.11 x L-shaped hex wrench 1.5mm (for M2 screws)Applications:Rapid function verification and prototypingIndustrial control and automationHome control systemsData collection and sensor monitoringEmbedded system development and learningWireless communication and IoT projects
