UNIT-Digi-Clock is a 2.1 inch 4-digit 7-segment display module. There are decimal points on each digit and an extra wire for colon-dots in the center, which can display Decimals and Clock.
This module adopts TM1637 as the driver IC, and STM32F030 as I2C communication. I2C address can be modified per 4-bit dip switch. The red LED supports 8 brightness. And we have reserved 4 fixing holes there.
