4 Bits 7 Segment Display Module for Arduino Projects

0.36"  7 segment LED Display with clock point

The module is a 12-pin display module with a 4-point common digital tube (0.36 inch) with a clock point. The driver chip is TM1637. It only needs 2 signal lines to enable the MCU to control the 4-bit 8- Segment digital tube.

Features:
Digital Tube: 4-digit common anode with a 0.36-inch digital tube with a score point,
highlighted in red
Positioning hole: 4 M2 screw positioning holes, the hole diameter is 2.2mm, which makes
the module easy to install and position, and realize the module combination
Digital tube 8-level grayscale adjustable
Control interface level can be 5V or 3.3V
Size: 42 x 24 x 12 mm
Weight: 8g
