LED Display Module with Serial Interface (TM1637 Chip)

Technical Specifications

• Power supply: 3.3 V – 5 V
• Low current consumption
• Limit resistors included
• Control transistors included
• Wavelength: 640 nm
• 4 pins for selection and 8 pins for each digit and point
• Dimensions: 33.5 x 21 mm

The module is a 7-digit LED display ready for use. LEDs are linked in common anode configuration.

For each digit, there are pins A, B, C, D, E, F, G and DP respectively for the point following the digit. Representing segments with letters is the universal one.

This module is useful for electronic assemblies with Arduino development plates in which you need to display numerical data such as temperatures.
