Arduino Micro 48mm x 18mm prototyping module

SKU CH-C0MZ-ZZ5RQ

Compact 48 mm by 18 mm prototyping module with Leonardo-class power for embedded projects

  • Product typePrototyping Products
  • Compact 48 mm x 18 mm module fits tight project spaces
  • Breadboard-ready layout speeds up prototyping on the bench
  • Solderable castellations allow permanent PCB integration
  • Developed with Adafruit for maker-focused accessory support
  • 9 in x .7 in footprint matches Leonardo capability in less room

Compact 48mm x 18mm form factor

The Arduino Micro delivers Leonardo-class functionality in a 48mm x 18mm module that measures 1.9 inches by .7 inches. Its small footprint suits makers who need to embed programmable logic directly inside space-constrained projects. The board works equally well plugged into a breadboard or soldered onto a custom PCB for permanent integration.

Headroom for embedded logic

The module provides enough I/O and processing capability for typical sensor interfaces, actuator control and USB communication tasks. Projects that demand large numbers of simultaneous high-speed peripherals or extensive onboard memory will exceed the available resources. Builders needing more pins or higher throughput should plan for a larger development platform.

Adafruit accessory ecosystem

Collaboration with Adafruit Industries has produced a growing range of add-on boards and accessories designed specifically for this module. These extras simplify power management, display attachment and wireless connectivity without custom PCB work. Makers who prefer to design every peripheral from scratch will not benefit from the ready-made ecosystem.

Questions about this item

Will the 48mm x 18mm module fit on my existing breadboard without adapters?

The board is designed to plug directly into a standard solderless breadboard or be soldered to a custom PCB, matching the compact 1.9" x .7" footprint.

How can I confirm the module is running correctly after I solder it to my custom PCB?

Upload a simple blink sketch through the USB connection; the on-board LED will flash if the microcontroller is powered and executing code.

Does the package include header pins for breadboard use, or must I buy them separately?

The module ships without headers installed; you will need to purchase and solder your own pin headers for breadboard or PCB mounting.
