What is M5Stack?

M5Stack is a modular hardware and software platform for IoT and embedded development. The “M” stands for modular design, “5” comes from the original 5 × 5 cm form factor, and “Stack” reflects the stackable design concept. By combining controllers, functional modules, and other expansions, users can move more efficiently from concept validation and prototyping to building real-world applications.

Controllers

Core Series

The Core series integrates display screens, buttons, speakers, microphones, batteries, and expansion interfaces. Main products include Core (Basic, Gray, Fire), Tough, Core2, CoreS3, Tab5, etc.

Stick Series

Slim and compact in form, the Stick series is designed for wearable, portable control, and mobile interaction scenarios, combining display, wireless connectivity, and sensing capabilities. Main products include StickS3, StickC Plus, StickC Plus2, StickC, StickT2, and more.

Cardputer Series

Combining a screen, keyboard, and portable body, the Cardputer series is designed for handheld terminals, mobile development, wireless communication, and AI interaction. Main products include Cardputer, Cardputer v1.1, Cardputer-Adv, Cardputer Mesh Kit, and CardputerZero.

Atom Series

Tiny in size, suitable for embedded applications, IoT nodes, and portable projects. Main products include Atom-Lite, Atom Voice, AtomS3, AtomS3U, AtomS3R, AtomS3R-CAM, etc.

Stamp Main Control Series

Shaped like a stamp, it is the smallest form of main control product, usually embedded in different functional bases to form a complete usable product.

E-Paper Series

Using electronic ink screens, with low power consumption, suitable for scenarios that require continuous display of information. Main products include PaperColor, PaperMono, PaperMono-Lite, Paper, PaperS3, etc.

Expansions

Unit Series

Including a variety of sensors, actuators, interface extensions, motor drivers, human-computer interaction (screens, lights, buttons, knobs, etc.), audio-visual cameras, communication and other functional units. They can be easily connected to various main controls through the HY2.0-4P Grove interface to add corresponding hardware functions.

Module / Base Series

Including various sensors, actuators, interface extensions, motor drivers, human-computer interaction (keyboards, buttons, knobs, etc.), audio-visual, communication, batteries, LLM and other functional units. Divided into four categories according to shape and size: Module, Module13.2, Base, and Faces, they can be easily stacked and connected to Core series main controls through M5-Bus (supporting multiple product stacking) to add corresponding hardware functions.

Hat Series

Including various sensors, actuators, interface extensions, motor drivers, human-computer interaction (buttons, knobs, etc.), audio, communication, batteries and other functional units. They can be easily connected to Stick series main controls through 8pin pin headers to add corresponding hardware functions. They are called Hat series because the installation method is like putting a hat on the Stick main control.

Atomic Series

Including various sensors, actuators, interface extensions, motor drivers, audio-visual, communication, batteries and other functional units. They can be easily connected to Atom series main controls through 4+5pin pin headers to add corresponding hardware functions.

Stamp Expansion Series

Similar in shape to the Stamp series main controls, they can be used for PCB mounting or embedded in other products to add corresponding hardware functions.

Chain Series

The Chain series is a modular, horizontally daisy-chainable hardware platform comprising controllers and input, sensing, display, and audio nodes. Each node communicates over UART and connects through dual HY2.0-4P interfaces, enabling flexible combinations for macro pads, smart homes, and creative interactive projects.

Interface

HY2.0-4P Grove Interface

A modular universal interface that allows quick connection of various sensors, actuators and other peripherals without soldering, enabling hardware debugging. It has an anti-reverse insertion design.

M5-Bus

A stackable bus interface used by Core series main controls and Module, Module13.2, Base series peripherals, consisting of two rows of 15pin 2.54mm pitch pin headers.

Software Drivers

M5Unified

M5Unified provides a unified hardware driver for various series of main control products. This driver library abstracts the differences between different hardware, provides a unified interface, and simplifies the experience of cross-device development.

Quick Start

M5GFX

M5GFX is used to handle the display of graphical interfaces, providing rich drawing functions and APIs. It also integrates multiple screen drivers and touch drivers.
