M5Stack Cardputer - Should this be legal?

i am Very excited for this one introducing the Cardputer. A high-performance card computer designed for engineers. The new version features the brand new StampS3A main controller, with optimized 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-inch 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. Additionally, an infrared emitter provides external infrared control interaction capabilities. For expansion, the built-in Grove interface facilitates custom sensor expansion; for storage, a Micro SD card slot is available for easy storage expansion.

The power system uses an internal 120mAh 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 LEGO hole expansion. This product is widely applicable in various scenarios such as rapid function verification for engineers, industrial control, and home control systems.
