| Overview |
| ******** |
| |
| `M5Stack-Cardputer`_ is a card-sized portable computer that is perfect for engineers. |
| At the heart of Cardputer is the M5StampS3, a mini development board based on the ESP32-S3 |
| chip. |
| |
| The 56-key keyboard and 1.14" TFT screen allow users to easily enter and view |
| information. The on-board SPM1423 digital MEMS microphone and built-in speaker |
| enable voice operations such as recording, wake-up and audio playback. The |
| infrared emitter allows infrared control interaction with external devices such |
| as TVs or air conditioners. And Cardputer offers a HY2.0-4P interface for |
| expanding I2C sensors such as temperature and humidity sensors, light sensors |
| and pressure sensors. It also includes a Micro SD card slot for expanding storage. |
| |
| The device is powered by an internal 120mAh+1400mAh (in the base) lithium |
| battery solution. |
