Gravity: 4-Digital LED Segment Display Module (Green)

This green 4-digit LED segment display module is a great choice. It has an 8-segment × 4-digit display mode and supports 8-level brightness adjustment. It uses IIC communication for efficient data transfer. The module operates at a DC 5V voltage with an operating current of less than 55mA. It can work in a wide temperature range from -40 ºC to +85 ºC, and can be stored at temperatures between -55 ºC and +125 ºC. The digital tube size is 5.05×1.9cm (2.0×0.75”), and the PCB size is 6.7×2.2 cm (2.64×0.87”).

Using this display module is easy. First, connect it to a power source with a DC 5V voltage. You can adjust the brightness according to your needs, with 8 levels to choose from. When using it, make sure the temperature is within the operating range of -40 ºC to +85 ºC. Avoid exposing it to extreme temperatures outside the storage range of -55 ºC to +125 ºC. For maintenance, keep it clean and dry. If there are any problems, check the connections and make sure the power supply is stable.
