The CJMCU-4051 74HC4051 Analog Multiplexer/Demultiplexer Breakout Board is a versatile module designed for efficient signal routing in Arduino and microcontroller projects. Equipped with the 74HC4051 SP8T analog switch, it provides eight independent channels for input/output selection using three digital control pins (S0, S1, S2). With a wide analog input voltage range of ±5V and low “ON” resistance, it ensures minimal signal loss. Logic level translation allows seamless communication between 5V logic systems and ±5V analog signals. Its compact 30 x 19mm design makes it ideal for prototyping, signal multiplexing, and sensor interfacing. Featured By RoboticsBD.
