- Use 4-digi 3.6” 7-segment display, common anode, 12 pins
- Only need two control pins, CLK and DATA (DIO)
- Use common 7-segment control IC TM1637, widely used together with 7-segment in many cases, for example, small instruments, domestic appliance, etc. Also very simple peripheral circuits for TM1637. (Datasheet of this IC is NOT available now, only in Chinese)
- Available to adjust brightness, 8 level gray scale
- Control signal can be 5V or 3V3
- 4 * M2 installation holes
- Arduino library (for TM1637) supported.
