Overview
The 7-Seg RGB Click Board™ carries a full-colour single 7-segment digit display. The click is designed to run on a 3.3V or 5V power supply. It communicates with the target microcontroller over the CS, and PWM pin on the mikroBUS™ line.
The 7-Seg RGB Click Board™ can be connected in a chain, in order to display a larger number of characters. Unlike conventional 7-segment displays, you will be able to use multiple colours on the display.
Display Features
Each segment has R, G, B LEDs that can be adjusted in 255 steps and therefore 16,581,375 colour combinations are available for each segment of the digit on the display.
Also, the ability to control the brightness of all the LED's is driven at 255 steps. It should be noted that brightness values above 80 should rarely be used.
