DescriptionCardputer v1.1 is a high-performance card computer designed for engineers, offering significant upgrades over the original version. It features the new StampS3A main controller with optimized antenna and button design, enhancing system stability and user experience.The device includes a 56-key keyboard and 1.14-inch TFT screen for efficient operation, along with an onboard SPM1423 digital MEMS microphone supporting recording and wake-up functions. Audio output is handled by a cavity speaker, and an infrared emitter provides external control capabilities. For expansion, it offers a Grove interface and Micro SD card slot.The power system combines an internal 120mAh battery with a base 1400mAh lithium battery, integrating charging and boost-buck circuits for extended battery life. The base includes magnets for metal attachment and LEGO-compatible expansion holes.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 LEGO hole expansionDevelopment Platform:UiFlow2Arduino IDEESP-IDFPlatformIOIncludes:1 x Cardputer V1.11 x L-shaped hex wrench 1.5mm (for M2 screws)SpecificationsSpecificationParameterStampS3AESP32-S3 (Xtensa LX7), 8MB Flash, Wi-Fi, OTG, CDCFlash8MBStorageSD CardKeyboard56 keys (4 x 14)Buttons1 x Reset button 1 x User buttonGrove1 x HY2.0-4PBattery Capacity120mAh 1400mAh (in base)Screen[email protected] Inch, 240 x 135pxCavity Speaker8Ω@1W I2S@NS4168MicrophoneMEMS Microphone@SPM1423Infrared Distance∠0° Infrared emission distance (straight line): 410cm ∠90° Infrared emission distance: 66cm ∠45° Infrared emission distance: 170cmSleep CurrentDC [email protected]Working CurrentIR emission mode: DC 4.2V/148.07mA Keyboard mode: DC 4.2V/138.93mAOperating Temperature0 ~ 40°CProduct Dimensions84.0 x 54.0 x 19.7mmProduct Weight90.0gPackage Dimensions145.7 x 95.0 x 20.7mmGross Weight106.8g
