Module array color random
Description:
Features: 8 Bits, 8 keys, 8 LEDs, 8 digital tubes, common cathode LED digital tube.
With TM1638 Chip, this module gather more than three common SCM peripheral circuits.
The advantage is only three IO ports will be occupied when it drives.SCM doesn't need to work for scaning display and key scaning.
It only need to read the relevant register to send display data or test button so it save MCU resources effectively.
Keys are sensitive and display effectively.
