Keyestudio EASY plug 4-Digit LED Display Module for Arduino STEM

The Keyestudio EASY plug 4-Digit LED Display Module is a compact, user-friendly screen designed for students, educators, and hobbyists building Arduino STEM projects. Featuring a 0.36-inch common anode display, this module is perfect for adding numerical readouts like clocks, timers, or scoreboards to your builds. It integrates seamlessly into the EASY plug ecosystem for rapid, solder-free prototyping.

Efficient TM1637 driver chip

The module utilises the TM1637 driver chip to control the 4-digit LED display using only two signal cables. This minimises the I/O pins required from your microcontroller, leaving more ports free for other sensors.

EASY plug RJ11 connection

With its pins extended into a registered jack, this display connects seamlessly to an EASY plug control board using a simple RJ11 cable. This solder-free connection is perfect for classroom environments and rapid prototyping.

Clear 0.36-inch LED display

This 12-pin common anode LED display features a 0.36-inch screen with score points, making it highly suitable for digital clocks, counters, and scoreboards. Note that this module must be used in conjunction with an EASY plug control board.

Standardised pin configuration

The display interface breaks down into four essential pins: GND for ground, VCC for power supply, DIO for data input/output, and CLK for the clock signal. This straightforward layout simplifies troubleshooting and coding in the Arduino IDE.

Robust and safe specifications

Operating at a standard DC 5V, this module functions reliably across a wide temperature range of -40 to +85 degrees Celsius. It is also RoHS compliant, meeting international standards for environmental safety.

Compact physical dimensions

With physical dimensions of 50mm by 23mm by 18mm and a weight of just 9g, this lightweight module is easy to mount on any robot or smart home project. It is fully supported by Arduino software tutorials and wiki guides.
