Control and adjust the brightness of multiple RGBA LEDs using the PCA9745B
LED Driver 16 Click is a compact add-on board that simplifies the control of multiple LEDs. This board features the PCA9745B, an SPI-configurable sixteen-channel constant current LED driver from NXP Semiconductors. Each LED output has an 8-bit resolution (256 steps) fixed-frequency individual PWM controller that operates at 31.25kHz with an adjustable duty cycle from 0 to 100% to allow the LED to be set to a specific brightness value. Powered through a selected mikroBUS™ power rail, either 3.3V or 5V, it provides a maximum output current of 57mA per channel and multiple built-in protection functions that protect the circuit during abnormalities.
This Click board™ is optimized for dimming and blinking Red/Green/Blue/Amber (RGBA) LEDs for various consumer amusement applications, LED status signalization, and many more.

ABOUT CLICK BOARDS™
Click boards™ follow a modular prototyping add-on board standard invented by MIKROE, which revolutionizes the way users add new functionalities to development boards. Click boards™ enable design engineers to change peripherals easily, cutting months off development time. To enable hundreds of Click boards to be connected to the microcontroller or microprocessor, we have invented socket standard - mikroBUS™. This uniform connection interface allows you to connect any Click boards to a main board instantly. The company releases a new Click boards nearly every day at 10am, and many leading microcontroller companies including Microchip, NXP, Infineon, Dialog, STM, Analog Devices, Renesas and Toshiba now include the mikroBUS™ socket on their development boards.
ABOUT MIKROE
MikroElektronika (MIKROE) is committed to changing the embedded electronics industry through the use of industry-standard hardware and software solutions. In 2011, the company invented the mikroBUS™ development socket standard and the compact Click Boards that use the standard to dramatically cut development time. Now the company offers 1300+ Click Boards – ten times more than competitors - and the mikroBUS standard is included by leading microcontroller companies such as Microchip, Renesas and Toshiba on their development boards. MIKROE defined MCU development add-on boards and socket standard called SiBRAIN, and display board and display socket standard - DISCON. MikroElektronika also makes the world’s widest range of compilers and additionally provides development environments, development boards, smart displays and programmers and debuggers.
