Grove - 0.54" Red Quad Alphanumeric Display

This 0.54" display has four bright red 14-segment characters, allowing you to present numeric and alphanumeric information. Powered by the TM1637 driver, it requires only two I/O pins for control (one for data and one for the clock), freeing up your microcontroller for other tasks. This makes it a great choice for resource-constrained projects where you need to maximise pin availability. It is ideal for many projects, from counters and clocks to more complex systems requiring a clear readout. With the Grove connector, integrating the module into your project is straightforward and hassle-free, allowing plug-and-play connectivity with various Grove-compatible boards such as Arduino (With a Grove - Base Shield) or Raspberry Pi (Only with the Grove-Base HAT). Its small size and low power consumption make it perfect for portable and battery-powered devices. Features
