Arduino Nano Terminal Expansion Board Screw Terminal Adapter With nRF24L01 Interface DC Power Connector Nano Shield For Arduino Nano Development Board

🚩 Nano Terminal Expansion Board V3.0

📌 Product Overview

This upgraded Nano expansion terminal adapter board is specially designed for Arduino Nano controller. It perfectly leads out all digital pins, analog pins and power pins via 3.5mm screw terminal blocks, eliminating messy jumper wires during wiring. The new version adds an independent DC power jack, built-in filter capacitor, and reserved nRF24L01+ wireless module expansion socket, greatly improving circuit stability and expandability for robotics, sensor experiment and DIY automation projects.
