10×10 RGB 2 Click

How does it work?

10×10 RGB 2 Click is based on the IN-PC20TBT5R5G5B, an RGB LED with integrated IC from Inolux. At its core, the 10×10 RGB 2 Click showcases a dynamic grid of 100 “smart” RGB LEDs configured into a compact 10×10 display. These LEDs stand out for their dual-wire transmission capability, encompassing a three-channel (RGB) smart control circuit for driving and illumination. Noteworthy features include a signal decoding module, a data buffering system, an inbuilt constant current circuit, and an RC oscillator. The whole solution is tailor-made for various applications, such as LED-based display screens, vibrant LED string lighting, and ambient scene illumination.

The IN-PC20TBT5R5G5B is made with CMOS technology, ensuring minimal voltage requirements and reduced power consumption. It supports 256 grayscale levels for PWM dimming and offers 32 levels of brightness control. The RGB LEDs on the board exhibit distinct characteristics for each color: the red LED operates within a wavelength range of 620-630nm and delivers a light intensity between 100-200mcd, the green LED features a wavelength span of 520-530nm with a brightness of 300-500mcd, and the blue LED emits light in the 460-475nm range with an intensity ranging from 50-100mcd.

The diodes are designed to function exclusively on a 5V supply sourced from the mikroBUS™ 5V power rail. To accommodate this, their control is managed through the LSD0102, a bidirectional voltage-level translator from Texas Instruments. This design choice ensures compatibility with both 3.3V and 5V MCUs, enhancing the board’s versatility. A special feature of these diodes is the existence of two output signals, data and clock, routed on test points next to 5V and GND test points on the back of the board.

This Click board™ can operate with either 3.3V or 5V logic voltage levels selected via the VCC SEL jumper. This way, both 3.3V and 5V capable MCUs can use the communication lines properly. Also, this Click board™ comes equipped with a library containing easy-to-use functions and an example code that can be used as a reference for further development.
