UNO R3 Prototype Expansion Board is a prototype expansion board designed for Arduino UNO R3, which is convenient for users to build and debug prototype circuits in the development process. The expansion board contains a large number of soldering holes for connecting various electronic components and modules, supports the breadboard function, and provides specialized power and ground terminals for convenient circuit layout. It also contains a variety of interfaces that support seamless connectivity with the UNO R3 motherboard, enabling developers to easily test and verify their designs. This expansion board is particularly suitable for users who are rapidly prototyping their hardware. specificities Large prototyping area: A large number of standard soldering holes are reserved on the board, allowing users to easily solder a variety of components, such as resistors, capacitors, LEDs, sensors, etc., for flexible circuit layout. Integrated Breadboard Function: Supporting breadboard-style connection, developers can connect components without soldering through the jacks on the breadboard for temporary circuit design and testing. Complete power supply interface: The board provides dedicated power and ground terminals, which can directly draw power from the UNO R3 motherboard, providing stable power supply and reducing the complexity of external power wiring. Dual-row expansion interface: Directly connected to the Arduino UNO R3 motherboard via dual-row female sockets, the board perfectly extends all the I/O pins of the UNO to ensure compatibility and expandability, while providing additional wiring points for easy experimentation and testing. Extra keys and LEDs: The board integrates some basic components such as user-defined keys and LEDs for quick testing of codes and interactive functions. Clearly labeled pinouts: Each pin and solder hole is clearly labeled with its function and location, making it easy for developers to quickly find the required pins and connect external devices. Why Choose Us The OpenELAB Prototyping Shield is an expansion board for microcontrollers in UNO design with which you can add your own circuits to your project. The shield supports you in the fast conversion of your own circuits in the grid size 2.54 mm. This shield offers additional functions as well as special features, such as additional mounting options for SMD components, two already soldered LEDs for direct control, a control and reset button, an additional ISP header and much more. Our Prototyping Shield is compatible with almost all UNO controllers on the market. Thanks to the included mini breadboard with 170 pins, you can also implement your circuit completely solderless. Low manufacturing tolerances guarantee a tight fit of your components on the breadboard.
