These 0.56” 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. These common-anode displays feature 4x 7-segment digits and one decimal point per digit. The LEDs have a forward current of 30mA. Connect Ground to pin 12,9,8 and 6. Insert 2.5VDC into pins 1 – 5, 7,10,11. See schematic to view pinouts. Pin 1 starts from the left with the first digit.

A big, bold, beautiful blue LCD with white back-lit pixels. This LCD is the graphical upgrade to those popular 16x2 LCDs, but allows full graphical control. Blue background with 128 x 64 'monochrome' white pixels. Low power white LED back-light. The LCD is driven by on-board 5V parallel interface chipset ST7920.

This is a chainable board equipped with 8 5050 WS2812 RGB LEDs in the smallest possible size. The WS2812s are each addressable as the driver chip is located inside the LED. Each pixel has ~18mA constant current drive so the color will be very consistent even if the voltage varies, and requires 5V.

This is a breakout board for the WS2812B RGB LED. The WS2812B is actually an RGB LED with a WS2811 built right into the LED! All the necessary pins are broken out to 0.1" spaced solder pads for easy wiring. Several of these breakouts can even be chained together to form a display or an addressable string.

This LED ring is addressable allowing users to chain multiple rings together to be run by one microcontroller. The LEDs surface mounted onto the ring are based on the WS2812 tech with the package size of 50x50mm. The LEDs operate at 5vdc so you can comfortable power the ring using only your microcontroller. Each LED draws ~18mA of constant current. Every ring is equipped with a single data line with a very time specific protocol requiring a real-time microcontroller with a 8MHz or faster processor to run it. This ring has a total of 24 LEDs with an outer diameter of 85mm.
