Start with the interface and connectivity you need: choose an integrated Core device for a screen-and-controller workflow, a compact StickC or Atom device for small prototypes, or a modular setup when you need to add sensors and communications. Check the product specification and expansion ports before choosing.

No. UIFlow provides a visual entry point, while Arduino IDE and PlatformIO suit code-based workflows. Use the software and documentation linked on this page to confirm support for the exact device before starting.

Compare the device interface, voltage requirements, pinout and firmware support with your existing hardware. The product page and official M5Stack documentation are the right references for model-specific compatibility.
