TM1637
Simple 4-digit 7-segment LED display driver module used for clocks and counters.
Best For
Projects needing 7-segment and Low cost with a commonly available displays part.
Avoid If
You need production-grade certainty without checking the exact module vendor, pinout, and library maintenance status.
Quick Decision Notes
TM1637 is indexed as a displays part from Titan Micro. ChipScout tracks it by practical maker-facing dimensions: interfaces, library readiness, estimated price, field-level sources, and whether the page is strong enough for selection rather than only lookup.
Technical Specifications
Common Use Cases
- Maker prototypes
- Low-cost modules
- Educational hardware
Known Issues
- Breakout boards may use different pin labels or regulator choices
- Clone modules can differ from the original datasheet part
Interfaces and Library Support
Every field is meant to be source-backed. Corrections should include a datasheet URL, vendor page, module photo, or reproducible library test.

Pinout Table
Pinout is not yet source-verified. Use the table as an integration checklist, then confirm exact pins against the module vendor page before wiring hardware.
Common Wiring
Power the module from a rail that matches the breakout board, not just the bare IC.
Connect ground between the controller, sensor/module, and external power supply.
Use a digital input, output, PWM, or ADC pin based on the module output type.
Arduino Example
void setup() {
Serial.begin(115200);
Serial.println("TM1637 GPIO wiring smoke test");
}
void loop() {
// Replace with the maintained TM1637 library or module protocol.
Serial.println("Read or toggle the connected signal pin.");
delay(1000);
}MicroPython Example
from machine import Pin
import time
signal = Pin(0, Pin.IN)
while True:
# Replace with the maintained TM1637 driver or module protocol.
print("TM1637 signal:", signal.value())
time.sleep(1)Recommended Development Boards
Good match for SPI/I2C displays and enough memory for UI experiments.
Simple 5V classroom baseline when the display module includes level shifting.
Useful MicroPython test target for SPI and I2C display drivers.
