Keyestudio Micro bit 4-Digit Tube Shield(Black and Eco-friendly)

The Keyestudio Micro:bit 4-Digit Tube Shield is an easy-to-use expansion board designed to enhance the digital display capabilities of your BBC micro:bit. Ideal for students, educators, and hobbyists, this shield overcomes the limitations of the micro:bit's built-in LED matrix by providing a clear, four-digit numerical display. It is perfect for projects requiring real-time data readouts like timers, clocks, and sensor displays.

Clear red numerical display

The shield features a red, 3.6-inch common anode digital tube display driven by the TM1637 chip. This makes it easy to read numerical data, overcoming the display limitations of the micro:bit's built-in LED matrix.

Straightforward pin connections

The shield simplifies wiring by connecting the micro:bit's P0 pin to CLK and the P1 pin to DIO. This pre-configured setup allows for quick programming and hassle-free integration.

Secure and easy mounting

You can easily fix your micro:bit control board directly onto the shield using five M3 x 6mm flat screws. This provides a stable and robust mechanical connection, perfect for classroom environments.

Compact and lightweight design

With dimensions of 52 x 52 x 10mm and weighing just 15.4g, this shield is highly portable and fits easily into custom enclosures. It is also RoHS compliant, ensuring it meets environmental standards.

Reliable electrical specifications

Designed to run on a DC 3.3V working voltage, the shield has a working current of 50mA and a maximum power draw of 200mA. It operates reliably in temperatures ranging from -20 to 60 degrees Celsius.
