Usually 4 digit display module is a 12 pin module. But in our Crowtail gadget, we utilize a TM1650 to scale down the controlling pins into 2 Crowtail pins. It only takes 2 digital pins of Arduino-compatible board or Crowduino to control the content, even the luminance of this display. For projects that require of alpha-numeric display, this can be a nice choice.

Features:

1. 4-Digit Display: Displays numerical information.
2. Simplified Control: Uses only 2 pins (Crowtail) thanks to the TM1650 driver.
3. Easy to Use: Control content and brightness with just 2 digital pins.
4. Compact Design: Smaller pin count than typical 12-pin displays.
5. Alpha-Numeric Capable: Suitable for projects needing to display letters and numbers.

Applications:

1. Time display
2. Stopwatch
3. Sensors’ input display

Package Includes:

1 x Elecrow Crowtail- 4-Digit Display
