Description
Cardputer is a card-sized computer designed for engineers, featuring an M5StampS3 as the main controller.
For human-machine interaction, it is equipped with a 56-key keyboard and a 1.14-inch TFT screen. The onboard SPM1423 digital MEMS microphone supports recording or wake-up functions, while the built-in cavity speaker enables audio playback. An infrared emitter provides IR control capability.
Expansion is provided via a Grove port for custom sensor connection, and a microSD card slot allows storage expansion.
Power is supplied by an internal 120 mAh battery plus a 1400 mAh battery in the base, greatly extending battery life. Integrated charge, boost and buck circuits are included.
The magnetic base can attach to metal surfaces and offers LEGO-compatible mounting holes.
Cardputer is ideal for rapid functional prototyping, industrial control, smart-home systems and more.
