Mikroe Bar Graph 4 Click

Mikroe Bar Graph 4 Click features the Texas Instruments TLC59283 16-channel, constant-current sink light-emitting diode (LED) driver. Each channel can be individually controlled with a simple SPI serial communications protocol depending on the operating VCC. It's compatible with 3.3V or 5V logic levels and comes with a constant-current value of all 16 channels set by a single resistor. It has one GPIO pin used to turn off all outputs during Power-On and output data latching to prevent unwanted image displays during these times.
