Unit DigiClock
SKU:U146
Description
Unit DigiClock is a 2.1-inch 4-digit 7-segment display module with a decimal point ( . ) and a colon ( : ), capable of displaying decimal points or time. It uses the TM1637 driver scheme, with the STM32F030 processor as the driver chip for I2C communication. Users can mount it onto the existing I2C bus of their devices, saving IO resources. The device I2C address can be modified using a 4-position DIP switch. The red LED display supports 8 levels of brightness adjustment. The board is equipped with 4 mounting holes.
