Are you tired of cluttered breadboards and tangled wires when experimenting with your UNO R3 control board and various sensor modules? This innovative sensor shield is designed to streamline your projects, offering a neat and efficient solution to power and connectivity limitations. Fully compatible with the UNO R3 control board, it effortlessly stacks onto your Arduino for immediate use. This versatile sensor shield extends all digital and analog ports of the UNO R3 into convenient 3-pin interfaces (G, V, S), allowing for direct and easy connection of 3-pin sensor modules. Furthermore, it breaks out essential communication pins with a 2.54mm pitch, including dedicated interfaces for serial, I2C, and SPI communication. For added convenience, the shield integrates a reset button and two signal indicators. A unique feature of this shield is its blue terminal blocks, which enable you to supply customized voltages to sensor modules. This is particularly useful for sensors that require specific voltage levels outside the standard 5V or 3.3V, providing unparalleled flexibility in your experimental setups. Extends the Arduino Reset button for easy access. Includes a built-in power indicator and a D13 indicator for status monitoring. Breaks out all digital and analog ports of the UNO R3 as 3-pin headers for direct sensor connections. Features a dedicated serial communication interface. Provides an I2C communication interface. Offers a SPI communication interface. Comes equipped with a URF interface. Includes an APC220 interface. Allows for supplying custom voltage to sensor modules via integrated terminal blocks.
