TM1638 Chip Key Display Module 8 Bits Digital LED Tube For AVR Arduino
Item No.: ME475
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.
