The M5Stack Proto Unit is a compact universal prototyping board designed for the M5Stack ecosystem. It connects to an M5Stack Core via the Grove port, giving you the freedom to build custom circuits and add-ons for your projects on a standard 2.54mm pitch perfboard.

Key Features

  • 70 Through-Holes – CNC-drilled 1mm holes on a 2.54mm (0.1") pitch grid
  • Grove Port Connection – Connects to M5Stack Core via the included Grove cable (Port B: GPIO36, GPIO26, 5V, GND)
  • Lego Compatible – Two Lego-compatible mounting holes for integration into builds
  • Compact Form Factor – Standard M5Stack Unit size

Ideal For

  • Custom sensor or actuator circuits for M5Stack projects
  • Prototyping add-on modules within the M5Stack ecosystem
  • Building one-off interface circuits with Grove connectivity

Package Contents

  • 1× Proto Unit (70-hole perfboard)
  • 1× Grove cable

Jargon buster

Plain-language definitions for the technical terms used above.

GND
GND is the ground or reference connection (0 V) for a circuit. When connecting two devices together, their grounds must be joined so both agree on what counts as a low or high signal.
Grove
Grove is a standardised 4-pin plug-in connector system for sensors and modules that avoids soldering and jumper wires, with different cable types carrying I2C, UART, analogue or digital signals. When a product is Grove-compatible it can be quicker to connect supported modules, provided the connector type, signal and voltage all match.
