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
