M5stack Cardcomputer StampS3 Microcontroller 56 Key Keyboard Card Computer DIY Electronics_qt5

Cardcomputer is a card computer suitable for engineers, using M5StampS3 as the main controller. In terms of control interaction, it is equipped with a 56 button keyboard and a 1.14-inch TFT screen for display interaction. In addition, the onboard SPM1423 digital MEMS microphone can record or wake up, and it is also connected to a cavity speaker for sound playback. It is equipped with an infrared emitter for infrared control interaction with the outside world; In terms of expansion, a Grove port is installed on the board, which can expand I2C sensors; In terms of storage, a Micro-SD card slot is installed on the board, which can be used to expand storage space; In terms of power supply, the internal configuration of a 120mAhand1400mAh lithium battery (in the base) provides power to the entire vehicle, greatly improving its endurance. It includes lithium battery charging and boost/drop circuits; In terms of structure, the base contains magnets for metal adsorption, and the structural settings are compatible with LEGO hole expansion. This product is used for engineers to quickly verify design, industrial control, home control systems, and more.
