Analogue Input Expansion Shield Kit for Arduino Uno

This self-assembly expansion shield electronic kit offers a quick and easy way to add an extra 24 analogue inputs to your Arduino UNO™ (or equivalent) board using just 4 I/O lines. Ideal for projects that call for more analogue inputs, e.g. sensor or robot projects.

This shield only uses 4 I/O lines (3 digital, 1 analogue) but adds a whopping 24 inputs, so in total you have 29 analogue inputs at your disposal.

• 24 analog inputs
• uses only 4 I/O lines
• stackable design
• complete with library and examples
