Grove - 4-Digit Display

A 4 digit display module usually uses 12 pins. In this Grove gadget the TM1637 is used to scale down the control pins into two Grove pins. This way It only takes two digital pins from an Arduino to control the content on the display, this even includes the luminance of the display. For projects that require a alpha-numeric display, this is a great choice.

Features:

• 4 digit red alpha-numeric display
• Grove compatible
• 8 adjustable luminance levels
