## Description

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. Cardputer features a powerful dual-core processor, supports Wi-Fi functionality and integrates various peripherals and sensors, making it ideal for rapid functional verification, industrial control and home automation systems. 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. Plus Cardputer offers a HY2.0-4P interface for expanding I2C sensors such as temperature and humidity sensors, light sensors and pressure sensors, which allows users to add different functional modules according to their needs and unleash their creativity. Cardputer also includes a Micro SD card slot for expanding storage space. Users can store program code, data files, images, audio and other resources on the Micro SD card. The device is powered by an internal 120mAh+1400mAh (in the base) lithium battery solution, eliminating concerns about battery life. In addition, Cardputer has built-in battery charging and voltage regulation circuits that automatically adjust voltage and current to protect the battery and the device. The base of the Cardputer incorporates a magnet, allowing it to be attached to metal surfaces such as fridges or whiteboards. What’s more, Cardputer's structure is compatible with building brick hole extensions, allowing users to create even more interesting designs using Lego bricks.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Endless hours of fun
*by O***U on 27 February 2025*

Very well build, great firmware support. Awesome little device.

### ⭐⭐⭐⭐⭐ Best M5 learning device available on the market
*by S***Y on 18 June 2025*

Why did you pick this product vs others?: Works great as a learning toy, can be used with SD cards which you could load with multiple operating systems The more powerful m5 stamp sips power, this thing lasts about 2 weeks before needing a charge. Literally fits in your pocket and could be used for multitudes of random tasks.

### ⭐⭐⭐ Questionable hardware issues
*by D***M on 28 March 2025*

Arrived in good condition and worked well for 2 weeks from delivery. The SD card functioned as expected until it failed to be detected after two weeks, despite appearing properly mounted. No visible damage to the pins. Afterward, the charging circuit failed and stopped charging entirely. I had to replace the BMS chip (originally TP4057 with 57B3 marking). Soldering a new chip didn’t resolve much, except for slow charging same as ESP32 chip having issues. Ordering is up to you, but this issue may not apply to all units. (Not to mention had some missing resistors and capacitors not critically)
