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.

Disassembly Notice When removing the StampS3 module from the front panel, be very careful with the FPC cable and connector on the back. Gently pull it out to avoid damaging the screen connector. Refer to the operation video in the Cardputer Accessory Kit .
