Sold in packs of five, it offers excellent value for hobbyists and professionals alike. ## Description Display device is 4-digit yang red digital tubeDigital tube 8-level grayscale adjustableWorking Voltage: 3.3V / 5v DCWorking Current: 30 / 80MALED Display: 0.36 incheColor: red highlightsThe driver IC is TM1637, only two signal lines can make MCU control four Digit 8-segment LED. Pinout: LED Display module to Arduino GND—ground (GND)VCC--power supply (5V)DIO--data input and output (D2)CLK--clock signal pin (D3) Review: They work great, an easy to use Arduino lib drives them. - Nice and bright, but not over-driven, good size and a fantastic price. Only minor issue is that they soldered the four-pin connectors on the wrong side, making removal required if you want to actually mount these to a panel. Be sure to bring your desoldering skills. Review: The 2 - 7 segment displays are soldered ofset - The 7 segment sections are uneven, numbers look shifted. Terrible quality control. ## Features - 4-Digit Digital Tube Display Module : The Driver Ic Is Tm1637, Only Two Signal Lines Can Make Mcu Control Four Digit 8-Segment Led.
