Arduino UNO R3 Screw Terminal Adapter Module Board Proto Shield V1.0 Expansion

🔧 UNO R3 Screw Terminal Proto Shield V1.0 | AuscomTech

This assembled shield converts Arduino UNO R3 power, analog and digital connections into convenient screw-terminal connection points while providing a central prototyping area.

External sensors, switches, relays and control wiring can be securely connected using the onboard 3.81 mm terminal blocks, reducing reliance on loose jumper leads. Additional solder pads and through-holes allow custom interface components or wiring to be incorporated directly onto the board.

Ideal for fixed prototypes, control panels, automation projects and development setups where secure field wiring and custom circuitry are required on the same shield.

⭐ Key Features

• Screw-Terminal I/O Access – provides secure connections for power, analog and digital pins.
• 3.81 mm Terminal Pitch – suitable for convenient removable wire connections during development and installation.
• Integrated Prototype Area – central through-hole section allows components, headers and interface circuits to be soldered directly onto the PCB.
• Double-Sided Soldering Area – component connections can be developed from either side of the prototyping section.
• Additional Connection Pads – rear I/O solder pads provide convenient points for flying leads and custom wiring.
• Reset Button – retains convenient access to the host board reset function when installed.
• D13 Indicator LED – onboard indicator provides visual monitoring of the corresponding D13 signal.
• Small Breadboard Support – centre section can accommodate a compact solderless breadboard for experimental circuits.
