M5Stack Cardputer with M5StampS3 v1.1

The M5Stack Cardputer v1.1 is a high-performance card computer designed for engineers, makers and hackers, offering a comprehensive upgrade over the original Cardputer. The new version features the brand new StampS3A main controller with USB-C, with an optimised antenna and button design for the core module, significantly enhancing system stability and user experience. In terms of control interaction, the product is equipped with a 56-key keyboard and a 1.14" TFT screen for efficient display and operation. It includes an onboard SPM1423 digital MEMS microphone supporting recording and wake-up functions, and outputs audio through a cavity speaker. An infrared emitter provides external infrared control interaction capabilities. For expansion, the built-in Grove interface facilitates custom sensor expansion; for storage, a MicroSD slot is available for easy storage expansion. The system is powered by an internal 120mAh lithium battery and a base 1400mAh lithium battery power solution, integrating lithium battery charging and boost-buck circuits, greatly enhancing battery life. Structurally, the base includes magnets for metal attachment and is compatible with building brick hole expansion. With a dedicated section on M5Burner for the Cardputer and endless community projects (some a little evil...), the Cardputer is an awesome tool for makers and hackers alike!
