Grove - 4-Digit Display
Availability
In stock
Grove 4-digit 7-segment display driven by a TM1637 controller, reducing control to 2 digital pins. Supports digit content and luminance control; compatible with Arduino and Seeeduino.
Pinout
- VCC
TM1637 modules are commonly powered from 5V; some breakout modules are sold for 3.3V-5V operation, but check the module's pullups and LED color before using 3.3V hosts
