These common-cathode displays feature 4 x 7-segment digits and one decimal point per digit. The LEDs have a forward voltage of 1.9VDC and a max forward current of 20mA.
Dimensions: 71.6 x 25.7mm
For a long time we ve had small 7-segment displays and huge 7-segment displays, but now we finally have something in between. These 20mm 4-digit 7-segment displays are big enough to see from a distance but not so big that you d have trouble finding an enclosure for them.
This WS2812 RGB Matrix consists of 8 independent WS2812 5050 RGB LEDs arranged in a rectangle format. The WS2812 5050 RGB LED is an addressable RGB LED which has uses the WS2812 driver chip.
The 1W High Power LEDs are comparable in brightness with the standard incandescent and halogen light bulbs. Not only are they bright, they also consume a fraction of power making them extremely energy efficient! This high power LED is mounted onto an aluminium heat sink. Simply connect the large + and – pads on the heat sink to activate the LED. This high power RGB LED is rated for R: 3V, G: 3.5V, B: 3.6V @350mA.
This WS2812 RGB Matrix consists of 64 independent WS2812 5050 RGB LEDs arranged in a 8×8 grid. The WS2812 LED driver chip allows these 5050 RGB LED to be independently addressed and controlled.
