TM1638 Digital 8Bit LED Tube 8 Keys Display Module for AVR
- Size:75mmx48mm/2.95"x1.89"(inch) (approx)
- The rated voltage: DC12V
- Voltage range: DC7.0 V-13.6 V
- The input power: 0.24 A
- The rated speed: 9500 R.P.M
- Temperature range:-10 - 70 ° C
- 8 Bits, 8 keys, 8 LEDs, 8 digital tubes, common cathode LED digital tube.
- TM1638 Chip, this module gathers more than three common SCM peripheral circuits.
- The advantage is only three IO ports will be occupied when it drives.
- SCM does not need to work for scanning display and key scanning.
- Only needs to read the relevant register to send display data or test button so it saves MCU resources effectively.
- Keys are sensitive and the display is effective.
