특징

  • HOW DOES IT WORK?

    2x2 RGB Click is based on the KTD2052A, a 12-channel RGB LED driver from Kinetic Technologies. It can be powered from mikroBUS™ socket supply rails, both with 3.3V and 5V selected over the VCC SEL. A 4-wire bus is multiplexed to reduce the pin count, as each pin on the bus integrates a switch to the input voltage and a programmable low-dropout current sink regulator. The driver is capable of 14 million colors with a controllable LED current from 125μA to 24mA in 125μA steps. There is also a night mode (8μA to 1.5mA in 8μA steps). There are 12 independent exponential fade engines with ultra-smooth 3072-step fade resolution and a 3-bit programmable fade rate.

    2x2 RGB Click uses a standard 2-Wire I2C interface to communicate with the host MCU, supporting clock frequency of up to 1MHz. The I2C interface allows you to set the ON/OFF status and individual LED current, as well as adjust the fade rate. An internal flexible pattern generator with a watchdog counter enables set-and-forget pattern executions, while more complex patterns may be executed from system firmware via the I2C interface.

    This Click board™ can operate with either 3.3V or 5V logic voltage levels selected via the VIO 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.
