It supports 4-digit numeric and letter display with 8-level adjustable brightness, operates on 3.3V or 5V DC, and requires only two signal lines for MCU control, making it an ideal, easy-to-integrate solution for Arduino and other microcontroller projects. ## 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: Great little display, but NOT I2C, and NO decimal points - It has the 4 pin I2C interface, but the chip has no slave addressing, so you can't put more than one display on an I2C channel. It does have a colon, if you want to display time, but NO DECIMALS. All five of my units came up out of the box, the library works great. ## 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.

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. ### ⭐⭐⭐⭐⭐ Great little display, but NOT I2C, and NO decimal points *by T***Y on February 19, 2026* It has the 4 pin I2C interface, but the chip has no slave addressing, so you can't put more than one display on an I2C channel. It does have a colon, if you want to display time, but NO DECIMALS. All five of my units came up out of the box, the library works great. ### ⭐⭐⭐⭐⭐ Great value, works well *by K***N on January 9, 2025* I got a pack of five for just eight dollars, which is a great price. These things can get really bright, so I use them at the minimum brightness. As others have mentioned, there is one flaw: the headers are soldered at an odd 45 degree angle on the face side, so they will most likely require re-soldering if you want to panel mount them. ## Frequently Bought Together - WWZMDiB 4 Digit 7 Segment Digital Tube LED Display Board for Arduino (5 Pcs) - ELEGOO 120pcs Multicolored Dupont Wire 40pin Male to Female, 40pin Male to Male, 40pin Female to Female Breadboard Jumper Ribbon Cables Kit Compatible with Arduino Projects - ELEGOO UNO R3 Board ATmega328P with USB Cable(Arduino-Compatible) for Arduino --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/486073245-4-digit-7-segment-digital-tube-led-display-board-arduino](https://www.desertcart.us/products/486073245-4-digit-7-segment-digital-tube-led-display-board-arduino) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-04-23*
