The NANO IO Shield V1.0 DIY (Welded) is a screw terminal expansion board designed to make wiring connections to the Arduino Nano secure, stable, and tool-free. Instead of relying on jumper wires that can loosen over time, this shield routes every available Nano pin to a labeled screw terminal block, allowing you to connect stripped wires directly with a simple turn of a screwdriver.
The “Welded” designation indicates that this version ships fully assembled, with all headers, screw terminals, and connectors already soldered in place. This makes it a ready-to-use solution for developers who want the reliability of screw terminal connections without spending time on assembly. Simply plug your Nano into the headers and begin wiring.
This shield is particularly valuable for projects that need to be reliable over the long term — permanent installations, industrial prototypes, field deployments, and any application where vibration or movement could dislodge a loose jumper wire. The screw terminals accept a range of wire gauges, making it easy to connect sensors, actuators, power supplies, and other peripherals with solid, dependable connections.
The board exposes all of the Nano’s digital, analog, and power pins in a clearly organized layout. Each terminal is labeled with its corresponding pin name, so you can identify connections at a glance without consulting a pinout diagram. This makes the shield a practical choice for both experienced developers who want faster assembly and beginners who are still learning the Nano’s pin layout.
The compact form factor preserves the Nano’s small footprint while adding the convenience of screw terminals, and the board can be mounted in an enclosure or on a panel for finished projects.
Whether you are building a control panel, a data logger, a motor driver interface, or a custom piece of equipment, the NANO IO Shield V1.0 DIY (Welded) provides a clean, professional way to make secure connections to your Arduino Nano.
