OUTLINE

M5Station-485

 

is a general-purpose IoT workstation in the M5Stack 

development kit series. It integrates rich interfaces and peripherals and is highly 
expandable. Large space reserved inside, flexible customization, and more likely to 
be applicable to various industrial acquisition and control application scenarios.
