Keyestudio NANO CH340 IO Shield For Arduino

The Keyestudio NANO CH340 IO Shield is a compact expansion board designed to simplify prototyping with your Nano microcontroller. It is ideal for students, educators, and hobbyists looking to build neat, secure, and solderless experimental setups. This shield makes connecting external sensors and modules quick and hassle-free.

Simplified prototyping and breakout

This compact IO shield breaks out all the pins of the Keyestudio Nano CH340, making it easy to hook up components for rapid experimentation. It eliminates the mess of tangled jumper wires on standard breadboards.

Secure mounting holes

The board features two onboard 3mm fixed mounting holes. These allow you to securely fasten the shield to your robot chassis, project enclosure, or experimental platform.

Robust terminal block connections

With a terminal block spacing of 3.5mm, this shield provides secure screw-terminal connections for external power and signals. This ensures your wiring remains intact even in mobile robotics applications.

Standard female header pitch

The shield features a standard 2.54mm female header pitch, ensuring direct compatibility with standard jumper wires and Nano-compatible boards. It allows for quick plugging and unplugging during development.

Compact dimensions and weight

Measuring just 53mm by 36mm and weighing only 20.5g, this shield adds minimal bulk to your projects. It is perfect for space-constrained builds and lightweight IoT devices.
